A discussion on making a deal
November 7, 2008
When Brian Hayes wrote a book review for American Scientist magazine in July, he didn't expect much reaction. But his mention of the Monty Hall dilemma, a probability puzzle that generated discussion in the mathematical community in the early 1990s, sparked a significant response, including a number of letters from people who, he says, "disputed the correctness of the correct solution."

Monty Hall dilemma
The Monty Hall dilemma came about as a result of the old television game show "Let's Make a Deal," where a contestant was told to choose one of three doors that a prize could be behind. The show's host, Monty Hall, would then open one of the two unchosen doors to reveal that there was no prize inside. A contestant could then either switch to the other unopened door or stay with the original choice. Debate continues over whether switching doors really increases a contestant's chance of winning.
