Before the end of the first round of cards, the teachers in the third grade office got the news.
"... Teacher Ma, that's how things are."
When Chen Chu finished his report with respect and respect, Ma Pingping was furious. She pushed the swivel chair away and stood up abruptly. Because the movement was too large, the swivel chair collided with the desk behind it, making a loud "bang".
All the teachers in the office were startled. Li Shu put down her pen, but hadn't recovered from the shock. Teacher Ma disagreed, so he went to class 1 to find someone to pick blackjack? Lin Zhaoxi was a little too noisy.
"Ms. Li, what's going on with the students in your class? If I don't study hard, will it still affect other classes?" Li Shu went directly to her desk and asked.
"What kind of tactic is this?" Li Shu muttered.
"Teacher Li!" Ma Pingping roared.
"Ms. Ma, don't be angry." Li Shu stood up and said, "Let's go and have a look."

"Your current 4 cards are 2, 7, 5, 6, and the total is 20. Unless you draw an ace, it will definitely explode. Are you sure you want more?" Lin Zhaoxi asked.
"want."
"Don't mislead others, okay!" Lin Zhaoxi was shocked, "My current cards are x, 2, 3, 3, and there is a rule in blackjack that the dealer must keep drawing cards until 17 before he has the right to choose whether to stop , I can tell you in advance that my points are not full 17, so I will take a card. In this case, your best strategy is not to, because you are already 20, and the chances of winning are great.”
"Anyway, it's a trial game without betting, whatever you want."
"Is your self-esteem ok if you lost to me directly after many years of fighting?"
"Is it okay to temporarily change my self-esteem?"
Lin Zhaoxi felt that what Zhang Liang said seemed to make sense, so she stopped arguing with him and continued to teach blackjack.
"After removing the big and small queens, there are now a total of 52 in poker, and there are 8 cards on the field, so there are 52-8=44 cards left. The probability that Zhang Liang does not burst is the probability of an a in the next card, that is..."
A boy next to "4/44" rushed to answer, "Less than 10 percent."
"No." Another girl retorted, "The hidden card of Lin Zhaoxi could also be an ace, it should be between 3/44-4/44?"
"6.8%-9%, the probability that the fifth card is an ace." Zhang Liang said, "Deal."
When Li Shu and Ma Pingping walked to the door of Class 1 classroom, what they heard was the last sentence.
In the corridor, the students surrounded the two who were playing blackjack. After a brief dispute, Lin Zhaoxi dealt Zhang Liang a card, and then it was her turn to choose whether to continue following.
Everyone held their breath and waited for her decision, so the atmosphere in the whole corridor was extraordinarily quiet.
"What are you doing!" Ma Pingping's roar resounded through the sky, "Stop studying, what are you doing here?"
The students were taken aback and trembled like an electric shock.
Ma Pingping separated the students and walked up to Lin Zhaoxi: "Who allowed you to gamble at the gate of our class, follow me to the Moral Education Office later!"
"Is this gambling?" Zhang Liang asked.
Ma Pingping: "Zhang Liang, let's see how you look now. The teacher is very disappointed in you."
Lin Zhaoxi raised her head: "Mr. Ma, there is one in the definition of gambling that you need to use something of value as a bargaining chip. Do we have a bet?"
"Why don't you even have a bargaining chip?" Zhang Liang was very dissatisfied.
The boys and the girls sang together, Ma Pingping's face turned green, it was ugly.
Chen Chu: "Zhang Liang, Lin Chaoxi, you are making excuses."
"Does it have something to do with you?" Zhang Liang said disdainfully, "A flatterer."
Ma Pingping's surname is Ma, so... Zhang Liang doesn't even pay attention to the teacher. This child is really more arrogant than when he was a child.
"Zhang Liang!" Ma Pingping raised her voice.
"Mr. Ma, the bell hasn't been rang yet, it's free time, why can't I play blackjack here?"
Chen Chu: "But blackjack is..."
"As I said just now, there is no bet, please have some understanding." Zhang Liang said.
"Are you the teacher or I am the teacher, I said you can't play, don't you have ears?"
As if she couldn't bear it at last, Ma Pingping's scolding sound bombarded the entire corridor, and the surroundings fell silent for a moment.
The students in class 1 looked at their head teacher with fear and doubt in their eyes, and the person with the strongest action stood up directly.
Zhang Liang put his hands in his pockets, turned around and left.
"What are you doing!" Ma Pingping asked.
"Go to the principal's office and ask the principal if we can play blackjack."
Zhang Liang said arrogantly, but he didn't take a few steps, but stopped suddenly.
The grade leader, Mr. Zhang, stopped him: "Young man, don't get too excited." The math teacher, who was nearly fifty years old, patted him on the shoulder.
A pair of dirty black leather shoes appeared in front of Lin Zhaoxi. She looked up and saw a bald old man.
"My classmate, what are you doing here?" the little old man asked her.
Lin Zhaoxi had just met this little old man in the office, and the other party had heard the whole thing from the beginning to the end, and now he asked it again, as if he was acting.
"Challenge Class 1." She spoke cooperatively.
"Why do you challenge Class 1 with blackjack?"
"Because Teacher Ma didn't want to give our ordinary class the chance to participate in the math league exam, then I have to win the class 1 and prove that it is unfair for Teacher Ma not to give our ordinary class a chance." Lin Zhaoxi replied.
"That's right, it seems to make sense." The grade leader old man Zhang said, looking at the head teacher of Class 1 who had always been aloof.
Ma Pingping: "Mr. Zhang, taking the exam in ordinary classes is a waste of their time. They should focus on preparing for the exam."
"It seems to make sense." Old man Zhang looked at Lin Zhaoxi again.
"But Mr. Ma is a math teacher in Class 1 and has never taught other classes. Why do you think this is a waste of time for other classes?"
"Then you guys have a fight."
Just as she was about to listen to Ma Pingping's speech, she suddenly heard the little old man say this. She froze, looking at the smiling teacher in front of her incredulously.
"As you say, don't make 'value bets'..."
The grade leader made the final decision.
"Great!"
"Long live!"
There were small cheers among the students.
"Ms. Zhang!" Ma Pingping couldn't hold back anymore, she said angrily, "As the grade leader, how can you condone such activities!"
"Blackjack is not such a simple gambling game. It involves so many simple to complex probability problems, profit calculation, and strategy selection. If children are willing to study in depth, our teachers should support it, which can enrich students' after-school life. "
"It affects their learning!"
"21 o'clock is also learning. Didn't the principal say it all? We need to find ways to educate students through various means to achieve the purpose of entertaining and teaching..."
The grade leader is the grade leader, and his awareness is higher than that of ordinary class teachers. Lin Zhaoxi was stunned when he heard it, and always felt that this flicker was very similar to Lao Lin later.
Lin Zhaoxi was stared at by old man Zhang: "Student Lin, when you are conducting your challenge, you should still remember to introduce chips, and tell other players the rules of 21, the probability calculation method you know, and how to formulate the best strategy. Classmates, pull you to the same level?"
"Huh?" Lin Zhaoxi was stunned.
"I mean, let's get started!" Old Man Zhang said.
—
"10 to k is recorded as 10, so 4/13 or 31% probability of getting 10..."
Ma Pingping had already walked away in high heels, when the lunch break bell rang, Lin Zhaoxi was taken to the classroom of Class 1, junior high school, and the round started again.
As the banker, in front of her was a hidden X and a 10, she swallowed, stupefied.
The round just now ended with Zhang Liang's explosive point, and the new round immediately reversed. She bit the bullet and continued to fight and teach.
But before she finished speaking, the children in Class 1, who were afraid of chaos in the world, shouted.
"What's that under you?"
"Are you about to lose?"
Lin Zhaoxi: "You can judge my hole cards by whether I continue to bet, but there is another possibility, if my hole cards are aces, one 10 and one ace, then I will get black directly, win directly and get the chips Double."
"What chips?" the students asked.
"I don't have any on hand now." Lin Zhaoxi looked around: "Are there many of the same thing that can pretend to be chips?"
"Buttons?" a boy asked.
"Do you take your clothes off?" the girl retorted.
"Is the bottle cap okay?" someone asked again. "There are a lot of waste plastic bottles that are going to be sold for money in the trash corner behind our class!"
"It seems possible." Lin Zhaoxi replied.
Hurrah, many students in Class 1 of the third grade rushed to the classroom and finally began to twist the bottle caps. There were eager conversations and the creaking of plastic water bottles one after another. Small bottle caps of different colors were thrown to the ground one by one, and some students even rushed back to their seats, Gululu finished drinking the water just to save the bottle caps.
Not long after, Lin Zhaoxi and Zhang Liang faced many colorful bottle caps.
Lin Zhaoxi: "We use the bottle caps as chips to make bets. You can choose to bet on one or all of them."
"How to place bets?"
"What are the odds?"
The atmosphere was warm, and students asked questions one after another.
"1 pays 1 for burst point, 1 pays for blackjack, and there is another rule that when the player only has two cards in hand, he has the right to choose to surrender and half of the chips can be returned. When the player follows the fifth card, the chips Also directly doubled." Lin Zhaoxi said.
"But how many bottle caps does each person have?" A classmate asked.
Lin Zhaoxi thought about it. This question involves the key to the competition system, and she couldn't answer it for a while.
"Each person has 10 bottle caps. If you lose all the bottle caps, you will be eliminated." At the end of the classroom, Pei Zhi added in due course.
Zhang Liang turned around: "Ten is too fast."
"After all, it's a battle of wheels, so hurry up." Pei Zhi replied.
