Answer + Explanation:

The Monty Hall problem is a famous problem in conditional probability and reasoning using Bayes' theorem.

How to explain the probability?

In the problem, you are on a game show, being asked to choose between three doors. Behind each door, there is either a car or a goat.

You choose a door. The host, Monty Hall, picks one of the other doors, which he knows has a goat behind it, and opens it, showing you the goat.

You know, by the rules of the game, that Monty will always reveal a goat. Monty then asks whether you would like to switch your choice of door to the other remaining door.

In conclusion, the solution is that switching will let you win twice as often as sticking with the original choice.
