I think the first question is 8 different ways because they will be ranked on a list of 8.

I think the second question is 8*8*8=512 ways the awards can be given out.....but im not sure if i did this right, please help!

chance that band 1 is top = 1/8

then chance that band 2 is second = 1/7

then chance that band 3 is third = 1/6

etc

so I claim

8! ways (big number, you compute :)

Now how many permutations of 8 taken 3 at a time (permutations not combinations because the order of prizes counts within each group of three) ?

n!/(n-r)! = 8!/(8-3)! = 8!/5! = 8*7*6

= 336
