The Monty Hall Problem
The Monty Hall problem is based on the television game show Let’s Make a Deal. While
I have never seen the show, it goes something like this:
Suppose you’re on a game show, and you’re given the choice of three doors: Behind one
door is a car; behind the others, goats. You pick a door, say No. 1, and the host, who
knows what’s behind the doors, opens another door, say No. 3, which has a goat. He
then says to you, “Do you want to swap and pick door No. 2 OR stay with door No. 1?”
The real question here is ‘do you switch?’ Intuitively, I think it makes no difference. I
you, so you can assume that really you only have a 50%/50% chance of picking the real
prize. No matter what door you choose, the host will eliminate a goat door, leaving one goat door and one prize door, so what difference does it make?
After many lively discussions around the dinner table, someone said: When you first
chose you had a 1/3 chance of picking the prize. Once the goat door opens, you have a
2/3 chance of picking the prize. Alright, I concede that my odds do increase after the
door is opened, but how do you get to 2/3? If I assume that I really only have a 1/3
chance of choosing the goat door because the host will eliminate the other goat door,
making my odds 2/3, does that encourage me to switch? What if I chose the prize in the
I remember seeing this problem recently, oh yes… one of my favorite movies, 21

variable change, I should switch. After the goat door gets opened my odds of choosing
the prize door increase to 2/3.
