There are five unmarked envelopes on a table, each with a letter for a different person. If the mail is randomly distributed to these five people, with each person getting one letter, what is the probability that everyone gets the correct piece of mail?

of course it is not 0 (not trying to be rude), because there is only one case and there are 5*4*3*2*1=120 cases total, so it is 1/120.
