Davit and Paul own a sailing boat that carries only two people. Four friends, Luke, Naomi, Rachel and Alana, would like to ride in the boat too. Since only David and Paul know how to sail the boat, at least one of these two must go oout in the boat whenever it sails. How many pairs could be chosen to go out in the sailing boat?

Well, the boat can only carry two people at a time, so it would have to have either David and one of the four friends in it or Paul and one of the four friends in it. So there are four combinations with David and four with Paul. That makes eight different pairs together. However, if David and Paul go out together, then there is nine different pairs.
