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. Essentially, you have to have doubles four. Well, there's only one outcome out of the 24 equally likely outcomes that meets that situation, this one right over here. So there is a 1 4th, sorry, 1 24th probability.
