That's the Monty Hall problem. It's also covered in the sequences.
Yes. That's another good one. I like hearing the stories of when Marilyn vos Savant answered the Monty Hall problem in her column and had hundreds of PhD's in statistics and engineering write in to tell her she was wrong. Funny stuff and also another really good example of where intuition can fall short.
