Suppose there is a red couch that seats 3, a blue couch that seats 4 and a green chair that seats 1. How many different ways are there to distribute the 8 people among the seats? (Without regard to the order in which they sit on the couches.) Suppose Sally and Bob still won't sit together (they won't sit beside each other, even if they are not on the same couch).
Assume that the furniture is in a fixed order and is not moved.
