How smart are you

Hassony · May 30, 2008

So you're in a game show, and the show host shows you 3 doors. Behind one door is a sports car worth $100,000, and behind the two other doors are two... goats.

You don't know what's behind each door, but the show host knows.

So you decide to pick door #1. You figure you have a 33.3% chance of getting the sports car.

However, after you chose door #1, the show host opens door #3 and reveals the goat behind that door.

So now, he asks you, "Would you like to change your answer and choose door #2 instead?"

If you're like most people, you will stick with your original choice since you figure that both door #1 and door #2 carry a 50% chance of you winning the sports car.

So what do you decide? Switch to door #2 or stick with door #1? In either case, why?
