They don't look the same, but they're both ones. Let's see, we have a two and a two. We have a three and a three. And we have a four and a four. And it's impossible to have a five and a five because the four-sided die only goes up to four. So there's four possibilities, four of the 24 equally likely possibilities involve rolling doubles. So there's a 424th probability, or if we divide the numerator and denominator by four, it is a 1 6th probability that Erica, a 1 6th probability that Erica rolls doubles.
