This one caused some years of debate amongst mathematicians, although the answer is well accepted now, so good luck.
In the game, you are a contestant on a game show and you are choosing one of three doors, hoping to win a car. Behind the three doors are (separately) two goats and a car. After you announce your choice, the host (Monty Hall) who knows where the car is, then opens a different door to reveal a goat.
You are then given the option to switch your choice to the remaining unopened door or keep your original choice of door.
Should you switch your choice to the other door, hoping to win a car - or will make no difference so you should stick to your original choice?
The answer is available online, please if you need to look it up don't post it.
