@triclops200(View Post) The one who doesn't switch has a 1 in 3 chance. By switching, you're effectively getting the sum of the probabilty of the other two doors, 2/3.
I could make a table, but I don't want to spend the effort. :P
@triclops200(View Post) Yeah, I know about it. By switching, you get a 2/3 chance of getting the car, by not switching you get a 2/3 chance of nothing.
