In statistics, when arrangement is done and the order does not matter, this is a permutation problem. This could be easily solved just by using your scientific calculator. The formula would be nPr, where n is the total size of people, and r is the number of person to be chosen.

Thus,

5P3 = 60

There are 60 ways.
