Yes, you should ALWAYS switch. At first this seems preposterous but here is why you should switch: Monty Hall knows which curtain has the prize and he will always show you the other one. If he were to pick randomly, you would have a 50-50 chance of winning on your final pick. But, because he knows, you have a 66.66% chance of winning if you switch. You can think of it like this, on your first guess, what was the chance that you would pick the prize? 33% - that's easy. So, after Monty reveals the curtain, what's the chance that you have the right curtain? It is still 33% because nothing has changed. Submitted 1/13/2000 11:49:42 PM
