Both of these cases are normal. So that means two out of four children or two out of four cases produce a color blind individual. And we know that two out of four is the same thing as 0.5. 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.
