Reviewing for my final exam can anyone please help access these problems?

a) How many ways can 11 football players stand in a circular huddle?

I put 11P11

b) 12 identical laptops are in the inventory of a dealer, and 2 have hidden defects. If 5 computers to be shipped are selected at random, find the number of ways that exactly 1 defective computer is included in the shipment.

I know I got this completely wrong and don't even want to put up what I had the answer that I got was 144

c)In part b) above, find the probability that exactly 1 defective computer is included in the shipment

once again since I got b wrong.....

d) In setting up a new department, a corporation executive must select a manager from among 4 applicant, 3 clerks from among 9 applicants, and 2 secretaries from among 7 applicants. In how many ways can these positions be staffed

I got 1C4 x 9C3 x 7C2 = 7056

e) A customer can purchase a sports car in either the convertible or hardtop model, in any of 6 colors, and with any of three accessory packages. How many options are open to the purchaser?

I got 2! x 3! x 6! = 8640
