Well, let's look at this. Actually, let me write it here. Let me do it in this, let me do it in a new color. So the probability of, I'll write and here in a neutral color, probability of A and B, probability of A and B is equal to, well, now we're looking at, once again, we have 24 equally likely outcomes. We have 24 equally likely outcomes. And how many of them involve A and B? Well, to get A and B, you have to have doubles and the four-sided die needs to be a four.
