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. So let's think about that. This is, she has rolled doubles, one and a one. They don't look the same, but they're both ones.
