Asmall company has 20 employees. six of these employees will be selected randomly to be interviewed as part of an employee satisfaction program. how many different groups of six can be selected?

There are several information's of immense importance already given in the question. Let us write them down first and then focus on the problem in hand.

Total number of employees = 20
Number of employees that has to be selected randomly = 6
Then
Number of different groups of
six can be selected = (20 * 19 *18 *17 *16 *15)/(6 * 5 * 4 * 3 * 2 * 1)
                                = 38760 groups
