Now when we go to selecting our vice president, we would have already assigned one person to the president. So we only have eight people to pick from. And when we assign our secretary, we would have already assigned our president and vice president, so we're only going to have seven people to pick from. So the total permutations here, or the total number of possibilities, or the total number of ways to pick president, vice president, and secretary from nine people is going to be 9 times 8 times 7, which is, let's see, 9 times 8 is 72, 72 times 7, 2 times 7 is 14, 7 times 7 is 49, plus 1 is 50. So there's 504 possibilities. So to answer the question, the probability of Marsha being president, Savita being vice president, Robert being secretary, is 1 over the total number of possibilities, which is 1 over 504. That's the probability.
