A committee of 5 is to be selected from a group of 21 people.
How many different committees are possible, given the following conditions?
b. One person is the chair and the rest are general members.
# of ways to pick the chairman: 21
# of ways to pick the remaining 4 people: 20C4

Total # of different committees: 21*20C4 = 101,745
