Explanation: Six students have a chance at the president slot, and then the vice president will be chosen from the remaining five. So there are (6)(5)=30 possibilities. You do not have to divide by 2, because the president-vice president combination is ordered; President Smith and Vice President Jones is not the same combination as President Jones and Vice President Smith.
