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
