Question

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?

Answer 1

How many ways can 5 objects be arranged?
The answer is 5! (or 5 factorial) which equals 5 * 4 * 3 * 2 * 1
The answer is 1 in 120 or (1 / 120) which equals 0.0083333333
