Question

A museum worker randomly displays 5 historical writings in a row. What is the probability that the worker lines them up from the oldest to the most recent from left to right?

Answer 1

The number of ways to arrange the 5 writings in a row is 5! = 5 * 4 * 3 * 2 * 1 = 120 ways.

There is only 1 way to arrange the writings from oldest to newest.

Therefore, the probability is 1/120.
