"How could none of them be right? You must have said this deliberately in order to win the gambling game. That must be the case!" Yang Wei stared at Zu'an fiercely, knowing how he thought he could be right. It turned out that nothing was right, how could it be possible.
"Yes, how could Teacher Yang do all the wrong things."
"He is an arithmetic teacher, Zuan is too much."
"In order to win the gambling contract, deliberately lie, it is really mean character."
……
Hearing the whispers of the surrounding students, Zuan did not get angry, but took out the paper he made and said: "Also, let you understand. Just look at the first question, the correct answer to these two The numbers are 2 and 2. What you wrote is 10 and 15. It looks like a random guess, right?"
Yang Wei’s old face became hot. He really guessed this question randomly, because the more he thought about it, the more confused he guessed the number, but he refused to admit defeat and said: "You are trying to make things difficult for this question. , How can this answer be derived based on these messy conditions?"
"Really?" Zuan smiled contemptuously. "If you don't understand, I'll explain it to you..."
"A knows the sum of these two numbers, but doesn’t know what the two numbers are. If you give 3, don’t you know 1+2=3? Give you 40, you don’t know 20 +20=40? Would you not know that 19+20=39? So there is a potential range, the "sum" should be between 4 and 38.
Then we start the reasoning from the situation where the sum is 4, 4=1+3=2+2, so A can't judge that situation.
Let’s look at B again. If the product of two numbers multiplied by B is 2, 3, 5, 7, 11, 13, 17, 19, etc., you can immediately infer The two numbers are 1 and the product itself, because there is only one way to split. But he said he didn't know, it proved that the number he held in his hand was not these.
Let's go back to A, suppose he got 4 in his hand, then according to B doesn't know to rule out the possibility of 1+3, then only 2 and 2 are left, which is eligible.
There are several other possibilities for any other number. A can't judge the two numbers so quickly, and B can't judge it immediately. "
Zu'an couldn't help sighing: "Look, as long as the method is right, the first number is tried out, isn't it easy? That's why I put it in the first question, which You don’t know how to do such a simple question, hey~"
People around him whispered:
"Hey, he seems to be very simple to say this."
"Cut, then why couldn't you do it just now."
"I just didn't expect it, you don't even think of Teacher Yang."
……
Hearing Zhou Jian's unteachable tone, Yang Wei's face flushed red: "Even if I made this question roughly wrong, then the next question, the probability of choosing which door is not Are they all the same, how could it be wrong!"
This is the first question he has done, and it is also the most confident question.
People around him echoed: "Yes, the probability of each door is not the same, shouldn't it be affected?"
Yang Wei's words do represent the common sense of ordinary people.
Zuan sighed: "It's just that their students made mistakes on this question. You, an arithmetic teacher, made the same mistake. It's really... hey..."
Seeing him eager to speak and then stop aiming at himself, Yang Weifei almost burst into anger: "Xio succeeded in gaining his tongue, but what did you say was wrong?"
The anger score from Yang Wei is +472!
Zuan said: "The door you chose has a one-third chance of getting treasures? The probability of winning the prize for the remaining two doors is naturally two-thirds. Now I help you Excluding one of the wrong options, is the probability of the remaining door two-thirds? Of course the door should be changed, so that the chance of winning is greater."
"Nonsense," said Yang Wei, "every door
The odds of winning are all independent and should be one-third. How could it suddenly become two-thirds? "
Zuan shook his head: "It seems that it is really difficult to understand such a complicated concept based on your IQ. Let me explain it in another way. If there are 10,000 doors in front of you, only one door has treasures. You choose a door at random. Is the probability of winning a prize only 1 in 10,000? Does such a small probability mean that it is impossible to win at all? The treasures are all in the remaining doors. Inside?"
"At this time, I opened 9998 of the remaining 9999 doors. The back is empty. I will ask you the same question. Don’t you want to change it?"
"Of course I have to change." Yang Wei said subconsciously, but his face changed as soon as he spoke. Is it true that he is really wrong?
"Your Excellency deserves to be an arithmetic teacher. You understand so quickly that you can teach you." Zu An nodded in satisfaction.
The top of Yang Wei's head is about to smoke. This guy is praising me on the surface, but why does it sound so harsh?
The anger point from Yang Wei is +333!
Zuan went on to say: "Next is the problem of pirates dividing stones. The best allocation plan for pirate armor is (97, 0, 1, 2, 0) or (97, 0, 1, 0, 2) , Look at your answer, right?"
Yang Wei immediately jumped up: "Nonsense, such a distribution plan is almost monopolized, how could other pirates agree?"
Zu'an shook his head: "They all said that these pirates are extremely smart people. They can rationally analyze the pros and cons. It seems that you are going to allocate it. Most of them are dead."
He didn’t sell Guanzi this time and said: “We use the reverse method. First of all, we will discuss with Pirate No. 5 because he is the safest and there is no risk of being thrown into the sea, so his strategy is also the simplest. It’s best if the people in front are all dead, then he can get the 100 yuan stones alone.
Looking at No. 4 next, his chances of survival depend entirely on the survivors in front of him, because if all the pirates from No. 1 to No. 3 feed the sharks, then if only No. 4 and No. 5 remain, no matter what What kind of distribution plan No. 4 proposes, No. 5 will definitely vote against to let No. 4 feed the sharks, so as to swallow all the stones. Even if No. 4 pleases No. 5 in order to save his life and proposes a plan of (0, 100) to let No. 5 monopolize the yuan, but No. 5 may still think that it is dangerous to keep No. 4 and vote against it to feed the sharks. Therefore, the rational No. 4 should not take such a risk and pin his hope of survival on the random selection of No. 5. Only by supporting No. 3 can he absolutely guarantee his own life.
Look at No. 3 again. After the above logical reasoning, he will propose a distribution plan of (100, 0, 0), because he knows that even if No. 4 gets nothing, he will still support him unconditionally and vote for it. Yes, then adding his 1 vote can make him secure this 100 yuan stone.
However, No. 2 also knows the allocation plan of No. 3 through reasoning, so he will propose a plan of (98, 0, 1, 1). Because this plan is compared with the allocation plan of No. 3, No. 4 and No. 5 can get at least 1 yuan stone. The rational No. 4 and No. 5 will naturally think that this plan is more beneficial to them and support No. 2 instead of 2. The number is out and the number 3 is assigned. In this way, No. 2 can successfully take away 98 yuan stones.
Unfortunately, Pirate No. 1 is not a fuel-efficient lamp. After some reasoning, he also got insight into No. 2's distribution plan. The strategy he will adopt is to give up No. 2 and give 1 Yuan Shi to No. 3 and 2 Yuan Shi to No. 4 or No. 5 at the same time, that is, propose (97, 0, 1, 2, 0) or (97, 0, 1, 0, 2) distribution plan. Since the allocation plan of No. 1 is more profitable for No. 3 and No. 4 or No. 5 than the plan of No. 2, they will vote for No. 1, plus No. 1’s own vote. 97 yuan stones can easily fall into the No. 1 pocket. "
The people around me took a breath: "These pirates are too smart too?"
"If there were such clever pirates in reality, it would be a terrible thing.
"
"Don't worry, this is just a hypothesis. How can such a powerful person in reality become a pirate."
"That's true."
……
At this time, Yang Wei had already lost sight of his eyes, stuck there stupidly, and couldn't hear anything.
Zu An suddenly became a little dissatisfied. He was broken so soon, don't you want to contribute anger to me? So he began to explain the correct answers to the following questions. As expected, none of Yang Wei's answers were correct during the whole process, but it was a pity that Yang Wei only contributed a few hundred points of anger, which was obviously completely broken.
"Oh my god, none of them are right. Teacher Yang is too bad, right?"
"Yes, he looks the most awesome in his nostrils on weekdays. I didn't expect his arithmetic skills to be so bad."
"Cut, it's not ashamed that such a person still comes to the college to be a teacher."
……
The gazes and cold words of the surrounding students pierced Yang Wei's heart like a knife. He roared and ran out of the classroom hurriedly, covering his ears. He didn't stop even if the people nearby called him. It was too shameful to want to leave this place as soon as possible. I thought I could easily trample on an ordinary student, but I didn't know it was trampled by the student. He knew that he had experienced this and he would never have the face to stay in the college.
As a teacher, as a result, I couldn't even solve one of the questions asked by the students. I am afraid that he will not only be the laughingstock of Mingyue City, but also the laughingstock of all the surrounding counties.
"Boss, you are too good!" Wei Suo ran over to him flatteringly, squeezing his shoulders and pounding his back. In addition, the classmates also ran over to bring tea and water. The other party's arithmetic ability, even if the slightest cultivation base can't. The future is bright and boundless, is it silly not to take advantage of this opportunity to fudge?
Chu also wanted to run over to talk to his brother-in-law, but he didn't know that there were so many people around him that he couldn't squeeze through, so he couldn't help but snorted: "A group of flatters."
Ji Xiaoxi's small face flushed with excitement, but at the same time secretly worried for him, if this offends the college teacher, will there be any bad consequences?
Pei Mianman showed a charming smile, which made the men next to her dizzy: "I used to regret the deal with this guy before, but now it seems that I might really get something back from him."
Zheng Dan in the distance glanced over the expressions of the women, and was secretly surprised. He thought that they were all rumors. Now it seems that Zuan and these women have a very close relationship with them. What kind of charm not only married Miss Chu, but also attracted these outstanding women?
At this moment, there was a violent shout: "Don't go to class well, what are you all around here, want to rebel?"
Hearing this sound, many people slapped their spirits. Obviously, this sound had caused too much shadow on them. They wore the striking Mediterranean hairstyle, holding a ruler in his hand, not the director of training, Lu Deyou who is it?
When he saw him coming, the people around him evaded a path automatically. He walked in and noticed that Zuan was sitting swaying and being pinched on his back by his classmates, frowning subconsciously.
However, when I saw the graceful Shang Liuyu on the side, his brows were twisted together and instantly stretched out: "It turns out that Teacher Shang is also here. What happened just now? I saw Yang Wei ran out with his face covered. , He won't listen no matter what you call."
"Maybe I feel a little embarrassed." Shang Liuyu smiled slightly, and roughly recounted what happened here. Her voice was soft and moving, even simply listening to her was an ultimate pleasure .
"Are you making trouble again?" Lu De's face was soft when he looked at Shang Liuyu, but his expression instantly became severe when he looked at Zuan.
