Kuaishou Wanjie Museum

Chapter 36 Key 50!

"Each person draws one card from the four cards of 5, 10, 20, and 50 each time, and the probability of getting each card will be [-]/[-], right?" Ruyu showed the posture of a teacher.

Both Jian Xuran and Geng Letian couldn't help but nodded, they still understand such a little math knowledge!

"The requirement of the game is that as long as the cards in your hand add up to 100, you can get an invitation letter.

No one could get one hundred in the first round of drawing, but there was a chance in the second round of drawing. "

Geng Letian's eyes lit up: "Yeah, if the first round of luck is very explosive and you get 50.

The second round of luck was also very explosive, and I still drew 50, so the sum is 100, and I can get the invitation letter! "

Jian Xuran is not optimistic about this: "Everyone knows the truth, but how many people can really make 1 in the first round and 50 in the second round?"

Ouyang Ruyu said without thinking: "One sixteenth."

"what?"

“第1轮能抽取到50的概率为1/4，结合前面第1轮，第2轮仍是能抽取50的概率则为1/16。

In other words, among a hundred people, on average, one out of every 16 people will draw 100 and become the lucky one. This probability is not low. "

"But it's still hard to achieve. If you don't get [-] in the first round, and you don't get [-] in the second round, what should you do?" Jian Xuran asked again.

"I can only pray for others to change cards, otherwise I will never get a hundred." Ruyu said lightly.

"Wait, don't we still have a third round? There is still a chance for the third round!" Geng Letian said hastily.

Ruyu shook her head, "No, there is no chance."

At this moment, her brain turned into a piece of data, doing precise data analysis.

“如果前面两轮都没抽到50，只在5、10、20这三个牌面中任意抽取两个相加，最大的牌面都不会超过40。

So even if 50 are drawn in the third round, there is no chance to form 100. "

Geng Letian and Jian Xuran were stunned for a while, and they couldn't turn the corner.

Ruyu said with a hammer: "So the winner of this game can be determined in the first two rounds of draws, and those who fail to draw 50 in the first two rounds will be eliminated!"

The faces of Geng Letian and Jian Xuran changed drastically, the cruel rules are slowly revealing their fangs!

"Then if 50 is drawn in one of the first two rounds, what is the probability that the cards will add up to 100 in the end?" Geng Letian asked hurriedly.

"A quarter." Ruyu calmly walked to the end of the line and lined up.

"The first key point of this game is 50, and the second key point is when you draw 50.

If it is drawn in the first two rounds, there is hope in the third round. If it is not drawn in the first two rounds, it is destined to be eliminated. "

Jian Xuran and Geng Letian hurriedly followed behind her.

Not for anything else, just because this person looks smart!

If you follow the boss, you shouldn't make any mistakes.

Jian Xuran said with some hesitation: "However, it is still a minority who can actually draw 100.

Even if 50 is drawn in one of the first two rounds, and there is hope in the third round, the sum of the three draws will never be exactly equal to 100, and there must be more numbers. "

Geng Letian somehow thought of it, suddenly realized, and quickly said: "So the clown can let us change the cards, we can change the extra cards with others!"

Ouyang Ruyu looked at Geng Letian approvingly, "It's not easy, you are finally smart!"

Geng Letian: "..."

Although it is a compliment, why does it always sound aggrieved?

Jian Xuran didn't expect so much, he breathed a sigh of relief, and murmured: "Yes, you can still change cards, anyway, as long as you get 50 in the first two rounds, everything is hopeful.

You must draw 50, you must draw 50..."

The two put their hands together to pray to God and worship Buddha. Jesus God Tathagata Buddha Avalokitesvara Bodhisattva Equal to Heaven and Great Sages all came to show their magical powers.

"Ah! Two 50s, haha, I drew two 50s, I got an invitation letter, hahaha, I got an invitation letter!"

In the hall, a tasker suddenly screamed and happily jumped around in place a few times.

The cards in his hand were shining brightly, and they were combined with each other in front of everyone.

"boom!"

A firework suddenly appeared from the top of the card, and the silver sequins shot out from it fell on the tasker's head and shoulders.

The sound of courtesy and music sounded, and the two 50 cards were automatically fused into a brand new 100 card, with "Invitation Letter" written on the back of the card.

This seemed to start a signal, and then the lucky ones appeared in piles, and both of them got two 50 in the two rounds, which were merged into a 100 invitation letter.

The person with the invitation was relaxed and comfortable, sitting on the other side of the casino, watching other taskers going crazy to get the invitation.

The team is getting smaller and smaller, and soon it will be Ouyang Ruyu's turn.

Both Jian Xuran and Geng Letian were very nervous, and there was another round of battle between the gods of the East and the West.

Suddenly, Geng Letian grabbed Ouyang Ruyu and asked nervously: "Wait, do you have any way to ensure [-]% clearance?"

Ouyang Ruyu gave him a blank look, "I can't affect the manipulation of cards, it's purely a matter of luck.

If I could control my luck, I wouldn't have joined this Myriad Worlds Museum at all. "

Not to mention being raped for a year for no reason, not to mention losing a year of memory, and even losing 50 years of life.

Alas, the more I think about it, the more I feel that I am unlucky and life is not easy, the cat sighs!
Jian Xuran laughed, "Forget it, don't complain, although there are many dangers in the Wanjie Museum, opportunities and dangers coexist.

As long as the task is completed, you can get general points to exchange for skills, and go to heaven and earth like the legendary fairy. Who wouldn't want to be so majestic?

Besides, you can live a long life! "

Ouyang Ruyu complained: "If this world can't survive, we don't know whether we will die or live, or we should stop thinking about such a long time ago."

Geng Letian couldn't help asking, "Why don't you look nervous at all?"

Ouyang Ruyu was already standing in front of the grid, reaching out to draw cards.

"If nervousness can bring me luck, I can be several times more nervous than you."

First card draw - 20.

She took another one without changing her face.

Second card draw - 5.

Ruyu's expression changed slightly, and she drew a card again.

The third card draw - 50.

The points of the cards drawn in three rounds are 75, and if they make up one hundred, there will be another 5 and 20, but this is almost impossible!

Not to mention whether it can be changed, it is very likely that no one will have these two extra cards at all!
"How's it going, how's it going, have you drawn 50, have you cleared the level?" Geng Letian and Jian Xuran both stretched their necks to see.

Ouyang Ruyu turned the cards down, but did not show them the numbers, "I didn't clear the level."
