re: Marilyn vos Savant and the history of the Montel Hall question

bbap, I thought it would be 50/50 as well at first. But expanding the scope to several doors helped me better understand that it does in fact increase your odds of winning by switching. As a few posters (myself included) have suggested, try using MANY more doors (100, 1000 etc) and then remove every door with a goat except for your initial choice and the last remaining door. The more doors you add, the more clear it becomes that you do not have a 50/50 chance by staying with your initial pick every time.
