And so let's see how many of them there are. There are one, two, three, four by one, two, three, four, five, six. So there are 24 possible outcomes, which makes sense. There's four possible outcomes for the four-sided die and six possible outcomes for the six-sided die. So you have a total of 24 equally likely outcomes. So probability of, let me write it here. So probability of A, probability of A is going to be the fraction of the 24 equally likely outcomes that involve event A, that she rolls doubles.
