Re: What are the odds of winning?

You have three doors to pick from. Suppose you pick door A, there is a 1/3 chance of it having the prize. So there is a 2/3 chance of it being behind B or C. If the host then tells you it isn't behind door B there is a 2/3 chance of it being behind C. So double the chance of that of it being behind A. Rather counter intuitive I know but numbers can be weird.
