And so that means we have a 50% chance that the child will actually be colorblind. Now, what is the probability that the child is not only colorblind but also male? And what that means is we want to look at that square that contains a male and that male is colorblind. And the case that we want to look at is this square right here. So we have only one of these four squares, satisfies condition B, where we have a male and that male is actually color blind. And so we have a one fourth chance, which is equivalent to zero point 25, which is equivalent to fifth or 25%.
