Our club has 20 members, 10 boys and 10 girls. In how many ways can we choose a president and a vice-president if we have no restrictions other than the same person can't hold both offices?

If the same person can't hold both offices, we have \(20\) people availible for the first office, and \(19\) for the second. \(20*19=380\).
