Chapter 89: Chip

Before the end of the first round, the teachers in the third office got the news.
"...Mr. Ma, this is the case."
Chen Chu Bi Gong Bi Jing reported the end, Ma Pingping was angry and burned. She pushed the swivel chair and slammed up. Because the movement was too large, the swivel chair hit the desk at the back and made a loud noise.
The teachers in the whole office were shocked. Li Wei put down the pen and did not ease it from the shock. Teacher Ma disagreed, went to class 1 to find someone to pick 21 points? This is too much trouble for Lin Chaoxi.
"Mr. Li, what is going on in your classmates, do you not study well, but also affect your class?" Li Wei went straight to her desk and questioned.
"What is this tactic?" Li said.
"Mr. Li!" Ma Pingping said.
"Mr. Ma is not angry." Li Wei stood up and said, "Let's go and see."

"Your 4 cards are 2, 7, 5, 6, and the sum is 20. Unless you touch an a, otherwise you will definitely be exploding. Are you sure?" Lin asked.
"Yes."
"Don't you mislead other people!" Lin stunned. "My current card is x, 2, 3, 3, and 21. There is a rule that the dealer must hold the card until 17 to have the right to choose whether to stop. I can tell you in advance that my points are less than 17, so I will take a card. In this case, your best strategy is not to, because you have already 20, and the win is very big."
"Anyway, there is no bet demo, whatever."
"After many years of fighting, lose directly to me, is your self-respect ok?"
"I will be ignorant of my self-esteem?"
Lin Zhaoxi felt that Zhang Liang said that it makes sense, so he did not bicker with him and continued to teach at 21 o'clock.
"Without the size of the queen, there are now 52 cards in total, and there are 8 cards on the field, so there are 52-8=44 cards left. The probability that Zhang Liang’s classmates will not explode is the probability that a card will appear a, that is..."
There are boys answering
4/44
,
10% less.

"No." Another girl retorted, "The dark card of Lin Linxi may also be a, should it be between 3/44-4/44?"
"6.8%-9%, the fifth card is the probability of a." Zhang Liang said, "licensing."
When Li Wei and Ma Pingping walked to the door of a classroom, they heard the last passage.
In the hallway, the students surrounded the two people who were playing the game at 21 o'clock. After a brief dispute, Lin Chaoxi sent Zhang Liang a card, and then it was her turn to choose whether to continue.
Everyone breathed and waited for her decision, so the atmosphere in the corridor was exceptionally quiet.
"What are you doing?" Ma Pingping snorted loudly. "Don't read, what are you doing here?"
The students were shocked and trembled with electric shock.
Ma Pingping separated the students and went to Lin Chaoxi: "Who allowed you to gamble at our doorstep, wait for me to go to the moral education!"
"Is this a gambling?" Zhang Liang asked.
Ma Pingping: "Zhang Liang looks at what you are like now, the teacher is very disappointed with you."
Lin Xiangxi looked up: "Mr. Ma, there is one in the definition of gambling. We need to use valuable things to make chips. Do we have a bet?"
"How come you have no chips?" Zhang Liang was very dissatisfied.
The boys and girls sang one and one, and Ma Pingping’s face was blue and ugly.
Chen Chu: "Zhang Lianglin, you are sophistry."
"Is it related to you?" Zhang Liang was very disdainful, "flattering."
Ma Pingping surnamed Ma, so... Zhang Lianglian did not even look at the teacher, this child is really more proud than when he was a child.
"Zhang Liang!" Ma Pingping pulled up the volume.
"Mr. Ma, I haven't ringed the bell yet, free time, why can't I play 21 here?"
Chen Chu: "But 21 is..."
"I have already said that there is no bet, and you have a little understanding." Zhang Liang said.
"Are you a teacher or I am a teacher? I said that I can't play. You don't have long ears?"
Like finally being intolerable, Ma Pingping’s blame slammed through the entire corridor and calmed down.
Class 1 students looked at their class teacher, and there were fears and doubts in their eyes, while those with the strongest action stood up directly.
Zhang Liang put his hands in his pocket and turned his head.
"What are you doing!" Ma Pingping asked.
"Go to the principal's room and ask the principal if we can play 21."
Zhang Liang said very proudly, but he did not take a few steps, but suddenly stopped.
Teacher Zhang, the grade leader, stopped in front of him: "Young man, don't be too excited." The math teacher who was nearly fifty years old patted him on the shoulder.
A pair of dirty black shoes appeared in front of Lin Chaoxi. She looked up and saw a bald little old man.
"This classmate, what are you doing here?" The old man asked her.
Lin Chaoxi just saw this little old man in the office. The other party clearly heard the end from the beginning, and now asks again, a little bit of acting.
"Challenge 1 class." She played very well.
"Why do you have to challenge class 1 with 21?"
"Because the teacher Ma is not willing to give us the opportunity to participate in the mathematics league exams in the regular class, then I only have to win the entire class of the class, and then prove that it is unfair for Teacher Ma not to give us ordinary class opportunities." Lin XI replied.
"It is like this, it seems a bit reasonable." Zhang Laotou, the leader of the grade, said, looking at the class teacher who has always been high.
Ma Pingping: "Mr. Zhang, taking classes in regular classes is a waste of their time. They should focus on preparing for the exam."
"It seems to make sense." Zhang Laotou looked at Lin Chaoxi again.
"But Teacher Ma is a math teacher in class 1 and has not taught other classes. Why do you think this is a waste of other classes?"
"Then you will play one game."
Just as she was about to listen to Ma Pingping’s remarks, she suddenly heard the old man say so. She stunned, and it was incredible to examine the smiling teacher in front of her.
"As you said, don't make ‘valued bets’...

The grade leader is hammered.
"Great!"
"Long live!"
There were small cheers among the students.
"Mr. Zhang!" Ma Pingping couldn't hold her face. She was angry and said, "How can you condone this kind of activity as a grade leader!"
"21 is not so simple □ □ game, it involves so many simple to complex probability problems, income calculations, and strategic choices, if the children are willing to study in depth, our teachers should support, can enrich students' after-school life? ""
"This will affect their learning!"
"The 21st point is also learning. The principals have not said it. We want to find a way to educate students through various means to achieve the goal of fun and education..."
The leader of the grade is the leader of the grade, and the consciousness is higher than that of the ordinary class teacher. Lin has a glimpse of it, and always feels that this flickering is very similar to the later Lao Lin.
Lin Zhaoxi was read by Zhang Laotou: "Lin, when you are carrying out your challenge, remember to introduce chips, tell the rules of 21, the probability calculation method you know and how to make the best strategy. Classmates, pull you to the same level?"
"Ah?" Lin 愣 愣 愣.
"I mean, let's get started!" Zhang said.

"10 to k is recorded as 10, so another 4/13 is 31% probability to get 10..."
Ma Pingping has stepped on the high heels and walked away. The lunch break started, and Lin Chaoxi was taken to the first class classroom and reopened a game.
As a banker, she was in front of a dark card x and a 10, and she swallowed her mouth and forced it.
In the previous session, Zhang Liang’s explosion was the end, and the new game was immediately reversed. She continued to play the game with her scalp.
However, she hasn't finished talking yet, and the class is afraid that the children who are not in the world will shout.
"What is the one under you?"
"Are you going to lose?"
Lin Zhaoxi: "You can judge my cards by whether I continue to bet, but there is still a possibility. If my cards are a, a 10 a, then I will get black directly, win directly and have chips. Doubled."
"What chips?" the students asked.
"I don't have it at hand." Lin looked around around: "Is there a lot of the same things, can you pretend to be a chip?"
"Buttons?" asked a boy.
"Do you take off your clothes?" The girl retorted.
"Do you have a bottle cap?" Someone asked. "The garbage corner behind our class is a lot of waste plastic bottles to sell money!"
"It seems to be possible." Lin dynasty answered.
Ula, a lot of students in the first class of the third grade rushed to the classroom and finally began to screw the cap, the eager conversation, the squeaking of the plastic water bottle. The caps of different colors were thrown one by one on the ground, and even the students rushed back to the seat, and the water was drained, just to cover the bottle.
Not long after, Lin Chaoxi and Zhang Liang faced many colorful caps.
Lin Zhaoxi: "We use the bottle caps to make chips, so we can choose to vote only one or all."
"How do you vote?"
"What is the odds?"
The atmosphere was warm and the students’ questions were one after another.
"Breakpoint 1 loses 1 and gets Black Jack 1 to lose 2. There is also a rule that when there are only two cards in the player's hand, they have the right to choose to surrender and can return half of the chips. When the player picks up the 5th card, the chip Also doubled directly." Lin said evening.

But how many caps do you have?
asked a classmate.
Lin Xiangxi thought for a moment, this question related to the key to the system, she could not answer at the moment.
"10 caps per person, lose all caps and eliminate them." At the end of the classroom, the time is added.
Zhang Liang turned back: "10 is too fast."
"After all, it is a wheel battle, hurry up." 2k novel reading network
