Problem 8

The Monty Hall Problem is a famous probability problem. It was featured in the 2008 film "21." In the 70s, the game show Let's Make a Deal was hosted by Monty Hall, and sometimes contestants would guess which door among three hid a large prize. After making their guess, Monty Hall would show the contestant one of the doors that did not contain the prize and offer the contestant a chance to change their choice of doors. This video explains the best strategy for winning the prize and the reason why it is the best.
