Monty Hall wants to make a deal. He asks you to choose one of three doors. Behind one door there is a brand new car! Behind the other two doors are goats.
After you have chosen your door, Monty Hall opens one of the doors with a goat behind it. He then asks you if you are going to stick with your first door choice or if you'd like to switch to the remaining door. What do you do?
Well, you might think, "There are only two doors left, so I have a 50/50 chance of winning. I'll just stick with my first choice."
Well, I'm afraid you are wrong. In fact, there is a 66% chance that the car is behind the other door. YOU SHOULD ALWAYS SWITCH.
It's pretty counterintuitive, eh? This video clip might help:
