T his function finds the number of different possible orderings in selecting r objects from a set of n objects. For example, there are six different ways of ordering the letters ABC in groups of three letters—ABC , AC B, BAC , BC A, C AB, and C BA.

The calculation equation is 3P3 = 3 x 2 x 1 = 6 (ways).

T his function finds the number of ways of selecting r objects from a set of n objects. For example, from the three letters ABC , there are three ways we can extract groups of two different letters—AB, AC , and C B.
