1) 9! ways = 362,880 ways
2) 4! x 12 = 24 x 12 = 288 ways
3) OSOGBO = 6! / 3! = 720 / 6 = 120 ways
4) C(12, 6) = 924 ways
5) 10! / (10 - 5)! = 10! / 5! = 10 * 9 * 8 * 7 * 6 = 30,240
6) EXAMINATION = 11! / [ 2! * 2! * 2! ] = 4,989,600 ways
7) 10 * 9 * 8 * 7 ways = 5040 ways
9) There are nine girl and six eligible boys. In how many ways can the committee be formed if there are four girls and three boys = C(9, 4) * C(6, 3) = 2520 ways
10) How many ways can a committee of two men and three women be selected from groups of eight men and seven women. C(8, 2) * C(7,3) = 980 ways
11) Anchor 1 man in any position.....the others can be seated in 4! ways = 24 ways
13 ) (1.06)^7 ≈ 1.5
14) P(7,4) - P(4,3) = 816
