Three Curtain Problem

[rstrats]

You are a contestant on a game show. There are three curtains. Behind one of the curtains is a new car. You are asked to choose one of the curtains. Lets say that you choose curtain #1. The host of the show opens curtain #3 and there is no car behind it. The host now gives you a choice. You can stay with curtain #1 or you can change your choice to curtain #2. The question now is: would it be to your advantage to stay with curtain #1, or would it be to your advantage to change to curtain #2 or would there be no advantage either way?

Monty hall problem eh? it's an interesting one, I would also recommend the "2 envelopes" problem if anyone finds this type of question appealing to think about.

The envelope problem uses the same principle.
