This, from the first round, assume that there are eighteen people, each with one bullet.
Common sense is that there are six magazines for a revolver. That is to say, assuming that the revolver is even, no one cheats, and the probability of everyone being shot is 1/6, then the person who falls is any of No. 1 to No. 18. 3~~
But this is also the case. Assume that 1~18 are arranged in order. Then, without knowing it, suppose that 1 is in front of 2, and 2 is in front of 3. If 2 is pulled the trigger, there will be bullets, then 1 will Die,
but 3 , who fired a gun slightly faster, killed 2 before 2 had time to fire, then 1 would not die, which is what the protagonist appeared in the second round.
We know that when the light is on, everyone has to pull the trigger, and 1~18 circle around the light bulb. It stands to reason that everyone should see the light on at the same time, but someone who shoots a gun quickly and has a bullet will eliminate the person in front of it. , Then the person in front will survive 100%.
In other words, whether the first round of death depends on the speed at which the person behind the gun fires. If the person behind is killed first by the person behind, this assumption does not hold. (A bit tangled), based on this, it can be deduced infinitely, that is, if the person shoots the gun fast and kills the one in front, the one in front will survive, and the one in front that survives has a 1/6 chance of dying. If it doesn't die, the one in front still has a 1/6 chance of dying.
Back to the original setting, three people died and 15 people remained. There are two bullets per person, which means that the probability of being shot doubles for each person, that is, the probability of death is 1/3. In this round, 5 people will die (on average), and 10 people are left, each with three bullets, then the probability of being shot is 1/2, so there are 5 people to die.
In the end, there are five people left, and two people are drawn to a duel, and the protagonist has a 2/5 chance of hitting again.
After that, there is a 1/2 chance of not dying and the protagonist did not die, and then a 2/3 chance of dying, and the protagonist did not die.
The probability of P being immortal = 1/6 × 1/3 × 1/2 × 2/5 × 2/3 × 1/2 = 1/540.
This is an estimate, and the ideal state of gun speed and light effects has not been calculated.
In the Super Lotto, the betting numbers are the same as the 5 front-zone numbers in the current lottery numbers (select 5+0), which means you will win the third prize. The third prize of the Super Lotto has a higher probability of winning. The third prize of the Super Lotto is the same as the first and second prizes, with a floating bonus. The prize amount increases with the current sales volume, which is the current prize amount minus the fixed prize amount 5%, the single bet bonus is divided equally. If you add up, you can get 60% more bonus. In theory, the 2 yuan single bet can get up to 5 million yuan, and the 3 yuan single bet can get up to 8 million yuan.
So, it's time for the protagonist in the film to buy the big lottery.
After that, he fainted smoothly. .
