A woman was followed by a man. The woman enters the elevator and the man follows. The woman asked the man to press the elevator first, the man pressed the second floor and the woman pressed the third floor. Before revealing the answer, let's analyze the place where the woman died.

In fact, the woman didn't die in the elevator on the third floor at all, but died after going out. That man won't do it in the elevator because there is a camera. If he wants to do it, he can do it directly in the elevator on the first floor.

When a man comes out of the elevator on the second floor, smiles at the woman, and then pulls out his knife and goes to the third floor, the normal person's first reaction is to press 1 floor immediately, and then press the close button on the third floor to go to 1 floor immediately. The man found out the woman's psychology and immediately ran to the 1 building in the middle or two thirds of the second floor (it is also possible to run back to the first floor when the elevator on the third floor goes down because there is plenty of time).

It should be noted here that the speed of ordinary men going downstairs can be flush with the elevator in the range of 5~8 floors, but they can't catch up with the distance above 8 floors, while the speed of going upstairs can be flush with the elevator in the range of 1-3 floors, but they can't catch up with the elevator above 4 floors. You can try if you don't believe me.

So what should this woman do? She has only one choice, and that is to light the elevator on the top floor immediately. On the third floor, she will stand in the corner of the elevator and wait for the elevator to close naturally. At this time, men will not rush in and start work, because starting work here is the same as starting work on the first floor, which is meaningless.

As soon as the elevator door closes, the man will catch up immediately when he gets to the top floor. At this time, the elevator is faster than people going upstairs. The distance from the third floor to the top floor is at least 10 floor (common sense: elevators must be installed in buildings above 13 floor, which is understood by architectural students). It takes about 10~ 13 seconds. In the meantime, women can press the alarm bell to use the alarm clock. The woman must throw the bag out immediately, and then press the floor 10, 7, 5, 3, 1 respectively. When they stop on each floor, they have to throw out their belongings, namely bags, coats, left shoes, right shoes and mobile phones.

Why are you doing this? Its purpose is to confuse men. Because when a man catches up with the top floor and finds the bag thrown out by a woman, there will be two doubts. One is that the woman ran to the rooftop, and the other is that the woman deliberately threw it out. If he chooses to catch up with the rooftop, the crisis will be resolved. If he continues to chase the elevator downstairs, he will see what the woman throws every three floors, and he will face the same choice, because he really doesn't know whether the woman is rushing out of the elevator or still descending in the elevator. In this way, the probability of his killing a woman is only1/2 *1/2 *1/2 *1/2 = 65438+64.

This probability can't kill anyone. If everyone can die, you can buy lotto next time.
