You’ve been invited to participate in The Monty Hall Show, where you can win a fabulous new car that’s behind one of three doors. Behind the other two, however, are goats. You pick a door, and Monty opens one of the other doors to reveal a goat. He then asks you: “Would you like to keep your door, or switch to the other closed door?” Assuming you want the car – a safe assumption – what should you do? This question, called the Monty Hall problem, is a classic from probability theory. Surprisingly, it does improve your chances of winning if you switch doors! Most people have a gut feeling that it doesn’t matter, but when you chose the original door, you had a one in three chance of getting the car. Now, you have a one in two choice, meaning, if you switch, you’ve got a 50% chance, rather than 33%. Now that we’ve answered that question, let’s ask the real one: Why does Monty want to get rid of this car so badly? Perhaps it just didn’t get his goat.
