If the awards are all the same, it is 28 C 5 which is (28x27x26x25x24)/(5x4x3x2x1)
If the awards are all different it is 28 P 5 which is 28x27x26x25x24
Do these out and see if you get one of those answers

b. 98,280
It is the combination of 28 choose 5. If you have a normal calculator you can do calculations like that on it.
Specifically, the formula is:
28! / [5! * (28 - 5)!]
