The role of probability in solving the Monty Hall problem

[robvalue]

I will tell you what you're doing wrong pool. You won't believe me, but I'll tell you.

You are over-simplifying probability. You're assuming that if there are two choices, they are equally weighted, regardless of what we know about them. That's just plain wrong.

I'm not convinced you guys even understand the game, so I'm going to have go give up. All I can say is go learn about probability. It's a useful skill.
