Real Cthulhu Running Game

  Chapter 1992 Achievement - Good Teacher

"Oh? Ah Peng, you should know what happened to the three-color ball game, right? I went to observe carefully that day and found that the people who participated in this game can be described as ten bets and nine losers, but I really didn't watch it. What's strange about those brothers of yours, because they didn't touch the bag containing the colored **** the whole time, and they all let the participants play by themselves; and the sign put out by your brothers, A Peng, has ten **** on it. A kind of reward and a kind of punishment, but why did those people get the punishment, if they were lucky, they got the lowest level of reward.”

Looking at Xia Fei who was puzzled, Liu Xing explained with a smile: "This is the charm of arithmetic. If you go to Zhuzi Academy to find someone who is proficient in arithmetic to study this game, he will soon find out about this game." You didn’t do any tricks, just relying on the probability problem to make money in an open and honest manner; if I remember correctly, there should be nine colored **** in three colors, right? And the only punishment is when you draw the colored **** The colors are four, three and two?"

"Probabilities? Logically speaking, each color ball has the same probability of being drawn. Why do you always get a ratio of four, three, and two? Shouldn't the ratio of three, three, and three be the highest?" Xia Fei Still puzzled said.

Liu Xing smiled again, shook his head and said: "If you insist on explaining this, it will be more complicated. After you go back, Brother Fei, you can find the corresponding number of colored balls, or marked chopsticks, and then you can draw one. A hundred times, you will find that the ratio of 432 far exceeds other possibilities; then you recall the signs displayed on the stall, and you will find that the rewards given by other ratios you have drawn are not counted. Many, because these ratios also belong to the kind of probability that is relatively easy to occur, so you have to go all in, unless you are very lucky, otherwise you will suffer a big loss 100%."

Even if Liu Xing said so, Xia Fei still insisted: "I understand the truth, and I watched the excitement for a while when I was idle and bored, so I also found that the frequency of 432 is the highest, but I just I don’t understand why it’s not 333? Logically speaking, 333 should have the most chances to play, right?”

Seeing this situation, Liu Xing felt a bit overwhelmed, because if he wanted to explain the probability problem in an easy-to-understand way, it would be easy to fall into the cycle of me proving myself. In short, the more I explain, the more people feel confused. . . What's more, Liu Xing can't explain it in an easy-to-understand way now, because Xia Fei and Yu Lei are two ancient people who have never been in contact with mathematics, or arithmetic. Let them understand what is called "probability". It is too difficult.

   This is like one of the most classic stalks on the Internet - why is this pigeon so big!

  To put it simply, if you put aside the possibility of purely playing tricks, the point of pigeon tricks is that some people don't understand "near big, far small", so he can't understand why pigeons are so much bigger than people.

So for Xia Fei and Yu Lei at this time, they really don't understand what probability is, they just think that the numbers of these three kinds of colored **** are exactly the same, so naturally it should be the best ratio to draw three, three, and three. normal.

  So now Liu Xing only feels a little headache, and he also begins to understand the difficulty of the teachers. After all, when your student falls into the misunderstanding of thinking about solving the problem, it is very difficult to get him out of the misunderstanding.

So Liu Xing thought for a while and said directly: "In fact, this is the case. If there are only two colors and the same number of colored balls, then if six are drawn, the ratio of three to three should be the highest, and it is also the most in our mind. The possible ratio, here we call it the expected value; and if it is a colored ball of three colors, then if we don't think about it, if we directly apply the expected value of the two colors, then we will think that it is three, three, three. most likely, but that's actually wrong."

"The reason is very simple. If there are only two colors, when you draw it, it is either this color or another color, so the probability of drawing them is almost the same. Just like you are free to toss a copper coin, either the front or the back, there are only a few The low possibility will stand up; but when it comes to three colors, the situation will undergo some subtle changes. It took a lot of time to experiment, and finally decided to use three colors of colored balls, each with nine colored balls, to set up a stall to make money."

   Fortunately, this is Tianshui Town. After squatting down, Liu Xing grabbed a handful of stones and divided them into three roughly equal parts.

"I will give you a simple analogy here, that is, remove the cloth bag, so that you can see clearly what happened when you took the colored balls! First of all, the three piles of stones here represent colored **** of different colors. The bag is of course mixed evenly, so I take out a ball of a random color every time; this process seems simple, but in fact it is very complicated, because we assume that the number of stones in the three piles is the same , then we have taken away one stone now, and there is one pile of stones less than the other two stones, so the possibility of me drawing this pile of stones is a little lower next time?"

As soon as Liu Xing said this, both Yu Lei and Xia Fei showed expressions of enlightenment, which made Liu Xing feel very relieved, and also understood why some people are good teachers, because it is indeed true to let others know things that they did not know before. It's quite fulfilling and satisfying.

   As a result, Liu Xing immediately realized that he was thinking too much. . .

Pointing to the other two piles of stones, Yu Lei said: "Since there are more stones in the other two piles, the probability of them being drawn is higher, but if they are also drawn with the same amount, then the three piles of stones Wouldn't the number be the same again?"

   Xia Fei on the side also nodded, expressing that he agrees with Yu Lei's idea.

  At this moment, if Liu Xing was not young, he might have suffered a cerebral hemorrhage from Yu Lei's anger. No wonder others said that the teacher had a very high probability of heart disease, which was caused by years of anger.

Liu Xing took a deep breath, then shook his head and said: "You are wrong to think this way, because this is the most idealized situation, it's like the two of you usually have routines when practicing martial arts, and it's very smooth to play one set , but if it is difficult to play this routine in actual combat, after all, you also need to adapt to the situation; it is like two martial arts masters who use the same martial arts. The latter is more powerful, but if the latter suddenly eats up his stomach, then he may not be able to win."

Speaking of this, Liu Xing took a few stones from that pile of stones again, "So in the real world, there may be the possibility of taking a certain pile of stones consecutively, so the possibility of the other two piles of stones being taken away The **** will continue to increase, but because the number of this pile of stones is large enough, it may still be taken away! Then the problem comes, since you all thought that the possibility of 333 is the most likely at the beginning, but now Four stones have been taken away from a pile of stones, so the one that has been taken away needs to be taken away from the other three miles, that is, four three two!"

   To become a martial arts master, understanding is definitely indispensable. Even Guo Jing, who looks simple and honest, is not stupid, let alone stupid, but has a better personality.

  So Liu Xing has talked about this, and Yu Lei and Xia Fei are finally enlightened.

   At this time, Liu Xing also received a message.

   "Congratulations to the player for triggering the high-difficulty achievement—be a good teacher (difficult)! Since there are no more than one hundred players who have obtained this achievement, you will get 1.5 times the achievement points."

"Being a good teacher: You will get this achievement when you teach NPC knowledge beyond the age. This achievement will give different grades of rewards according to the difficulty of the knowledge. Currently, there are three grades: easy, common, and difficult. "

"Remarks: This achievement can be triggered repeatedly, but you can't achieve it by imparting the same knowledge to different NPCs, and after repeated triggering of achievements of the same difficulty, the rewards you get will continue to decrease, and finally you can only get Guaranteed five achievement points."

   "Remarks for Remarks: Don't try to teach NPCs about nuclear energy and other related knowledge, unless you can create the relevant knowledge system from scratch, otherwise you will be regarded as a hypergame."

  Is there such an achievement?

Liu Xing was taken aback for a moment, and then realized that the game hall of Cthulhu Running Group really played a role in this martial arts module, because it may have already guessed some players, especially those who just joined Cthulhu Those players in the game hall of the Lurunning Group don’t like to fight and kill, not to mention that they are still fighting with real knives and guns there, so for the game experience of these players and the rewards they can get, the Cthulhu Running Group The game hall also prepared other ways for them to obtain achievement points.

For example, doing business around, or making all kinds of pills in the medical school, or blacksmithing like the three of Li Hanxing. If it doesn’t work, you can find a place to farm, because some players have triggered the farming task two days ago , that is to obtain the corresponding achievement points according to the weight of the grain at the time of harvest and the data per mu.

Therefore, the task of "Being a good teacher" is for those who want to be teachers, or who are teachers in the real world. Knowledge must be beyond the age of the content, it is impossible for you to teach the ancients piano, chess, calligraphy and painting, right? At that time, maybe there will be an offensive and defensive swap.

   All in all, Liu Xing felt that this achievement was not in vain because he and Xia Fei and Yu Lei had wasted so much talk. . . And I'm so tired.

Liu Xing looked at Yu Lei and Yu Lei who were in deep thought, and couldn't help sighing again, and he was also thankful that his two "students" were not bad in understanding, so he was able to understand what he wanted so quickly. to express the meaning.

But this also allowed Liu Xing to see a broad road, because there are a lot of points rewards for achieving this achievement. Although there are difficulty bonuses and top 100 ranking bonuses here, the achievement points after removing all these bonuses Not too little, the most important thing is that the difficulty of triggering this achievement is not high, that is, it only needs to spend a little brain cells, but if you can find a few good students and prescribe the right medicine, then you will get twice the result with half the effort.

What's more, Liu Xing has now discovered a bug, that is, the same knowledge can be taught by different players to different NPCs, which means that the alliance can publish a book "One Hundred Thousand Whys", and then players can take it with them. This book goes outside to find two suitable apprentices, and then you can start earning achievement points.

   If there are no accidents, this can at least earn four-digit achievement points! This is not a small amount. After all, Liu Xing still doesn't have so many achievement points, even with the addition of the achievement points he just obtained.

  But when a thing has an "if nothing unexpected" situation, then it is very likely to have an accident.

  So Liu Xing received a freshly released system patch.

"All players who have triggered the achievement of being a good teacher, please pay attention. In view of the fact that some players have used this achievement to obtain points on a large scale, there will now be a new note for this achievement, which is the same knowledge. In the same area, only It can be triggered a certain number of times, and the area here generally refers to the area of ​​influence of a certain city, please pay attention to your location."

Well, the loophole that Liu Xing just thought of was patched, which made Liu Xing feel a little depressed, but Liu Xing didn't feel depressed for long, and realized that the "probability" he taught hadn't let a hundred If a player triggers an achievement, then I can at least let Zhang Jingxu and others trigger this achievement, right?

  Thinking of this, Liu Xing found a reason to bid farewell to Yu Lei and Xia Fei who were still thinking about the problem, and then found Zhang Jingxu and others to inform the matter.

"Is there such an achievement? The Cthulhu running team game hall is really a conscience discovery this time. Since you are willing to let us players be teachers in the module? But it is hard work for you, Liu Xing. The probability looks like It seems quite simple, and we seem to be able to get started in elementary school, right? But if we really want to study in depth and systematically, we have to start after entering university, so we want to let some basic knowledge in the real world It’s hard for people to understand this color ball scam, let alone in this martial arts mod.”

Yin En said with a smile: "However, Liu Xing, you have already given us a good start, so it will be much easier for us to trigger this achievement, but I don't know that it is that unconscionable guy who is doing this in Liangcheng." Street scam."

"it's me."
