All-day duel with Hei Lian boyfriend

Hearing Yu Shen's speech, the boys and girls who were playing the game were taken aback. They looked up and found that it was a tall boy wearing the old school uniform.

Yu Shen repeated to the girl again: "Take the one on the table."

"Ah, good, good..." The girl came to her senses, and quickly picked up the covered card on the table.

After opening it, it turned out to be a little joker.

"What the hell are you doing?" Several boys stood up in a hurry and approached Yu Shen, "Who the hell let you in? Have you got permission!?"

"I didn't get it." Yu Shen's voice was very calm, "I came in when I wanted to."

Boys: "..."

"If I haven't remembered, violence is prohibited in the school." Seeing several boys staring at him, Yu Shen turned his wrist and said, "I don't mind. But let me remind you that if you do something, I'm afraid tomorrow You can’t come to school normally.”

When Yu Shen said this, his voice was cold, his expression was calm and composed, and his eyes showed undisguised contempt and contempt, which made it difficult for the boys to figure out who he was from for a while.

Many students in this school are either rich or expensive, if they mess with the wrong person, their lives may be ruined in the future.

"..."

The boys weighed it up and gave each other a look.

Immediately, a boy who seemed the kindest stood up and reasoned with Yu Shen: "But, we are in a normal game, and you suddenly broke in to point fingers at the players, it's not good."

"Normal game?" Yu Shen sneered, took the card from the girl's hand, pointed to a small gap on the card, and said word by word, "Are you sure, this is also called normal?"

"Fuck..." One of the boys changed his face, pointed at the girl and cursed, "That's what the female cousin did! What does it have to do with us?!"

"I didn't..." The girl's hair was disheveled, she shook her head desperately, and broke down in tears, "You are the ones who slandered me! You are the ones who slandered me..."

Her broken and crying appearance gradually attracted the attention of many passing students.

Yu Shen glanced at the girl, and sneered: "She did it herself? All right, then we'll call the executive committee to see if it was she who did it herself, or you guys are doing something wrong."

The executive committee that Yu Shen mentioned was an organization specially set up by Xiaozhong for the student war. Most of the people who worked in it were teachers of various subjects, who specialized in supervising and managing the order and discipline of the student war.

As soon as they heard about the executive committee, those boys were dumbfounded.

If we let the executive committee know about it, is that okay?

Seeing the girl's cries getting louder and louder, Yu Shen had no intention of backing down at all, the fat boy with a kind face from before stood up again, gave the girl the betting chip, and sent the two of them out anyway. It's over.

After leaving the club building, the girl was still sobbing and crying all the way, Yu Shen had nothing to do with her, so he had to send her to the bus station.

"I'm sorry, I'm sorry!" The girl didn't know how to stop her tears, feeling very sorry, "I'm really sorry for causing you trouble."

"Forget it." Yu Shen pointed to the nearby station, "I'll take you here, I'm going to take the tram on the other side."

"Wait a minute." The girl called him hastily, "Well, I..."

Yu Shen:?

"Can I treat you to a meal..." Her voice was very low, she looked at Yu Shen timidly, "If not, can you tell me your contact information? I can treat you another day!"

Yu Shen: "..."

"I think you must be hungry too." Seeing that Yu Shen didn't refuse, the girl became a little more courageous, "If you don't want to go too far, we can go to the cafeteria."

She seemed to be sure that Yu Shen would not refuse directly and bluntly, and she put forward several proposals one after another. Yu Shen couldn't help it, so she agreed to go to the cafeteria with her and ask some information about the new campus by the way.

Through conversation, Yu Shen knew that the girl's name was Wang Ruolan, and the club just now was the oil painting department.

A good oil painting club is keen to play poker, which shows that the student war has indeed pushed people to a certain level.

The cafeteria of the new campus is equally gorgeous, not to mention the waiters who shuttle back and forth, there is even a waterfall outside the glass door of the inner hall.

Yu Shen didn't have much appetite, so he ordered some curry and sat down.

Wang Ruolan asked: "How did you see that there was something wrong with that card just now?"

"There is no problem with that card." Yu Shen sprinkled chili powder on the curry, "I just said that it is more likely than the card in your hand."

This unexpected answer surprised Wang Ruolan: "Huh?"

"No problem?" She felt incredible, "No problem, how could I have lost so many times? Could it be that they cheated?"

"Chuqian... If you want to say it, it can be considered." Yu Shen thought for a while and said, "It's actually just a common probability problem. Have you heard of the Monty Hall Paradox?"

Wang Ruolan showed a dazed expression.

Yu Shen explained to her patiently: "The situation at that time was that you had already got a card in your hand, but you didn't know what it was. At this time, the president turned over a 5 of spades, and the flower card was only It may be the one in your hand and the one that has not been opened."

"Yes." Wang Ruolan felt terrified when she thought of this, and her expression was still not good. "The president forced me to take the remaining card. I was very scared. I couldn't believe him, so I thought it must not be that card... …But I didn’t expect it to be that one.”

"Normal." Yu Shen said, "Most people would think that no matter which of these two you choose, the probability is one in three, but that's not the case."

Wang Ruolan: "What do you mean?"

"You can assume that there are two sets, set one is your card, the probability of it being a flower card is [-]/[-], and set [-] is the remaining two cards, the probability of them being a flower card is [-]/[-] Two, if it has been determined that one of the cards is not a flower card, then naturally the remaining cards bear the two-thirds."

"So it's like this..." Wang Ruolan came back to her senses, "Then he deliberately scares me so that I don't dare to choose the card on the table."

"Yes." Yu Shen picked up the cup at hand and took a sip, "But they turned over a card that was not a flower card. From this point of view, they probably did some tricks."

Wang Ruolan was a little taken aback.Those boys were going to lie to her for sure, but she never expected that Yu Shen would stand up for her.

Thinking that Yu Shen might be picked on by those boys because of this in the future, she felt very sorry.

"Actually, it's okay if you didn't save me just now." Wang Ruolan said weakly, "I made an agreement with the student union that they won't be able to win all my bargaining chips."

Yu Shen had already started eating, so he didn't answer the conversation, but only motioned her to continue talking.

Wang Ruolan had a solemn expression, and explained to him something about the current situation of the new campus.

As the home of the student war, the new campus is far more intense than the old campus. In order not to be exiled to the old campus, some weak people who do not have the confidence to participate in the competition will seek help from the student union.

They made a written agreement with the student union, and handed over their heart chips and some ordinary chips to the student union, so that they had the capital to stay in the new campus.

But at the same time, they have also become slaves of the student union. As long as they are the instructions and orders of the student union cadres, they cannot disobey.

Yu Shen swallowed a mouthful of curry slowly and asked, "Who is the chairman of the student union now?"

"It's Liang Qingshu from the second grade." Wang Ruolan didn't seem to dare to call her by his name directly, and her voice was very low. "This method agreed with the student union was also thought up by him."
