Essay question due 7/16:
Note: You are welcome to use any resources to solve these questions. Just be sure to write your solution in your own words and reference sources that you use.
(The Monty Hall Problem) 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 number 1, and the host, who knows what's behind the doors, opens another door, say number 3, which has a goat. He says to you, "Do you want to pick door number 2?" Is it to your advantage to switch your choice of doors?
I encourage you to use other textbooks or the web in answering this question. Just heed the note above and be aware that there is no math web police checking the validity of posted solutions.
