The Monty Hall Problem #
Led to look into the topic by this column — which I never managed to finish — I just had to share this one. For lack of a better resource, I’m linking to the rather-good Wikipedia article. On the page, they explain the problem thusly:
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 pick door No. 2?” Is it to your advantage to switch your choice?
