The host's answer to the question resulted in a flood of letters from PhDs in mathematics and professors at major universities, many of whom disagreed with her and argued that switching doors does not improve your odds of winning.

04:26
The correct answer is the one given by Marilyn Voss-Savant - your odds would be better if you switch doors because your initial odds of choosing the correct door did not change when Monty opened one of the doors.
