Chapter 394 Who is the ghost?
Liang Qiu thought for a while before he understood what was going on.
"So that's the case, it seems that it's not difficult!"
His voice was a little annoyed.
Maybe he thought that he couldn't even answer such a simple question at that time, which was simply too bad.
"Although it's not difficult, it also requires calm thinking. However, the situation you encountered at that time may be difficult to calm you down. So what is the second problem?" Luo Xi had already gotten into the taxi, told the driver about the address, and leaned on the back of the chair. At the same time, a gap in the car window was slightly opened. The cool wind blew in, making people feel much clearer.
Liang Qi hurriedly passed the second question to Luo Xi.
"The second question is a bit like a sitcom, with the name, 'Who is the ghost'. This requires me to participate by myself. I have no idea what they are going to do. I feel that these 'disasters' are all ill in their brains, and they are very abstract."
It seemed that it had brought up some bad memories, Liang Qi couldn't help but curse.
"It's exactly like that. They put three chairs in the house, and two disasters will come out. In addition, I have three people in total. They want to play roles at random. There are two kinds of roles to play, one is ‘people’ and the other is ‘ghost’. But I don't know which one to play. I have to get one randomly from 5 hats with the ‘character name’ written on it. I wear it on my head. I can't see my own hat, but I can see the roles on other people's hats."
"What I already know is that among the five hats, 3 are 'people' and 2 are 'ghosts'."
"At that time, I will sit on the chairs with two other guys wearing hats. There will be a referee to ask, and he will ask everyone the same question, and he is asking."
"He asked, you are a human or a ghost, right?"
"Yes, yes!" Liang Qi nodded quickly, although Luo Xi on the other side of the phone could not see it at all: "This is the problem. How could I know I am a human or a ghost? Because I can't see the words on my hat."
"In other words, after asking everyone the same question, the referee asked you to say that you are a human or a ghost. However, strictly speaking, even if you are confused, you can still mistake it once if you try a few more times. Could it be that? The referee also asked you to explain the reasoning process clearly?"
"Luo Xi, you guessed it right. It's true. Even if I'm right, I can't explain the principle. This is simply bullying. If I can't pass these two levels, I will not be able to enter the third question. I really have no tricks on this matter, so I can only find you. If you can't do anything, I will be really desperate."
Liang Qiu's voice was filled with pleading.
Indeed, you can see your family by participating in the Disaster Star Game, but if you cannot pass the level, it cannot change the result of both your family and yourself being burned to death.
If you experience such things for too much, even a man who is strong will collapse.
"This game is actually very simple. Liang Qi, you are just in the environment at that time and can't think calmly." Luo Xi's words obviously relieved Liang Qi's mood a lot. He knew that Luo Xi was comforting him.
"Thank you Luo Xi!"
"You're welcome, let's talk about this game of 'who is the ghost'. In essence, this is a simple mathematical logic reasoning problem, with 5 options, 3 people, 2 ghosts. If only three people are arranged to sit on chairs, that is, there are only three possible situations, 1 and 3 people are all humans; 2 and 2 people are 1 ghost; 3 and 1 person and 2 ghosts"
Liang Qiu listened to Luo Xi's analysis and nodded.
That's true.
"The problem lies in the referee's question. He will only ask the person involved, are you a human or a ghost? The premise of this game is that you can't see whether the person is on your hat or a ghost, so for the three participants, there are only three answers, 1. Don't know; 2. I am a human; 3. I am a ghost"
"It seems that this is indeed the case." Liang Qi thought about it carefully and obviously came to his senses.
He is obviously not good at analyzing these things, he is good at solving problems with his fists.
"Then I ask you, because you can't see that you are a human or a ghost, so under what circumstances will they say 'I don't know', and under what circumstances will they determine 'I am a human', or 'I am a ghost'?"
Luo Xi raised a question to Liang Qi.
Because the latter needed to think, even the speed of the car dropped.
Otherwise, it is easy to drive directly into the ditch because of being stunned.
"I can't imagine!" Liang Qi decided to focus on driving. He didn't want to worry about it, and he had already asked Luo Xi for help. He just wanted to think about anything, just follow Luo Xi's arrangements.
On the other end of the phone, Luo Xi sighed: "Liang Qi, you must think it out by yourself, because the first two levels are not the key, and the last one is. Even if I help you and tell you the correct answer, how can you deal with the third question alone?"
This time, Liang Qi finally took it seriously.
He immediately slowed down the car, then stopped in the emergency lane, and turned on the vehicle's double flash lights. Luo Xi is right. He can only solve this problem. Luo Xi can only provide him with some ideas and make some advance predictions and reminders.
"I'll think about it." Liang Qi thought carefully, and then his eyes lit up: "If it were me, my answer must be based on seeing the 'word' on the heads of the other two people. Similarly, their answers should be the same."
"Yes, the answers of two people except you are the key to solving the problem." Luo Xi praised: "When the answer is 'not sure', the corresponding one is what I said before, the first and second of the three possibilities, that is, 3 people are all humans, or 2 people and 1 ghost. In the first case, what you see with each other is all 'people', that is, you can determine the identities of the two people, but you cannot determine whether you are a human or a ghost, so you can only answer 'not know'; similarly, if 2 people and 1 ghost, you can see the identities of the other two people, it may be 2 people, or 1 person and 1 ghost. Similarly, in this case, it is impossible to determine."
"So, can only be sure of the last situation? That's 1 person and 2 ghosts?" Liang Qi asked hurriedly.
"It's not the case. You have to know that the real player of this game is you, and everyone else is a cooperative character, so you must be the last answer, and your answer must refer to the answers of the previous two people, because they can see whether you are a person or a ghost on your head. If the rules of the game are that everyone does not allow everyone to lie, then you can indeed know whether you are a human or a ghost through this gameplay, but you need to think about this logical relationship yourself. If you don't know when prompted, then I can't help you."
Luo Xi said it very clearly.
Prompt is prompted, guide is guided, but the real problem is Liang Qiu himself.
Only when he thinks clearly about this logical relationship can he answer the third random question.
Luo Xi has roughly deduced the type of the third question through the first two questions. He will tell Liang Qi what he summarized, similar to the "formula", and let Liang Qi apply it himself.
But even so, Luo Xi is not sure whether the third question can be passed.
After changing Liang Qi's identity to Ke Lan, Luo Xi is sure that Ke Lan can complete the game without his own help.
No mistakes, one song, one content, one in 6, one book, one bar, one reading!
If it was Qian Fatty, after these tips, Qian Fatty could pass the level.
But Luo Xi really finds it difficult to make a prediction in Liang Qiu's words.
If you have to say a probability, it is possible that only 50% of the possibility is not even enough.
But this is also the limit that Luo Xi can achieve at present.
The same thing is said, in the scene, Liang Qiu could not call himself for help on the spot, and everything was up to him.
This time, Liang Qiu thought for a long time.
Luo Xi thought about it and gave a prompt again: "You need to use the assumption technique. Remember, assumption technique is a key to solving most logical problems."
"Assumed?" Liang Qiu finally figured out the key after smoking two cigarettes.
"I understand, Luo Xi, I understand, haha, because the other two people can see me. If the rules say that lying is not allowed, then I can use the assumption and the other party's answer to derive the answer."
"I am either a human or a ghost. If I am a ghost, then the other two people can see the situation, one ghost and another, because only in this way can they meet the conditions that they cannot be sure of being a human or a ghost. The answer given by the other party is the key prompt for me."
"Because one of their answers was 'not sure', so one of them and I must have a human being, and because I am a ghost, the other party must be a human being. Therefore, according to this principle, the other person can be sure that he is a human being, and then he will answer that he is a human being. If so, the assumption that I am a ghost can be valid. On the contrary, I am not a ghost, but a human being."
"That's right, so the key to this question is to assume the possibility and pay attention to the answers of the other two people." Luo Xi also breathed a sigh of relief.
This logical relationship is as simple as 1+1 for him, but he thinks that simple things are not easy to teach others.
Mastering knowledge and imparting knowledge are all two different things.
Fortunately, through guidance and reminders, Liang Qiu solved this problem.
"The most critical thing about the game is the third question. Although I have not participated in the Disaster Star Game, you can roughly infer the scope of the third question through your description and the first two questions, because the final result of this game is two possibilities. One is that the player fails to pass the level and causes disaster; the other is that the player succeeds to pass the level and prevents disaster, so this third question is likely to be a multiple-choice question, and you don't need to consider how to answer the process of making a choice."
"I, I don't understand." Liang Qi was stunned.
Luo Xi said in more blunt words: "The multiple-choice questions for the final game are either win or lose. Because I can't know what the specific question is, I can't help you answer, but I can give you a suggestion."
"What suggestions?" Liang Qi felt his heart beating, and he was very nervous at this moment.
"Don't think about it, make a choice immediately based on instinct. In other words, it's just a chance. If you have a card on hand that can increase your luck, you can use it at this time"
