You don't have to worry about that. You're just left with 5 times 4 times 3. Exactly what we had up here, 5 times 4 times 3. In general, if you wanted to figure out the number of ways to stick 2 things in 5 chairs and you don't care about differentiating between those 2 things, you're going to have this expression right over here, which is the same thing as this right over here. You're going to have n factorial over n minus k factorial. Then you're going to divide it by this expression right over here, which we already said is the same thing as k factorial. You're also going to divide it by k factorial.
