You can divide both by 2 again. And then this becomes a 1. This becomes a 17. And you could divide this and this by 3. This becomes a 2. And then this becomes an 11. So we're left with the probability of having all 4 1's in my hand of 9 that I'm selecting from 36 unique cards is equal to, and the numerator I'm just left with this 2, times 1 times 1 times 1.
