This program actually simulates the Monty Hall problem.
There are three doors, and only one leads to the prize. After you choose one, the host opens one of the other doors to reveal that it does not contain the prize. You are told you can change your choice—but should you? That is the question.
Please select the door you would open first from among 1, 2, and 3. Also, please specify the number of trials (how many times you’ll play the door-opening game). The program will then calculate the probabilities for both changing your choice and sticking with it.
The number of the first door to open
Number of attempts
Number of wins: If changed If left unchanged 
If you make any changes, %、If you do not want to change it, %There is a [probability] chance of winning.
The more trials you run, the more accurate the result will be, but it will take longer. Well, if you open a door over and over again, it’s going to take time, right?
As a rough estimate, 100,000 trials took about 30 to 40 seconds.
