That's a total of 714 trophies, I should have been a trophy maker!

When awards are handed out, often they award 3rd place first, then second, then first.

Actually, there are only 3 awards so THOSE 3 awards can only be present in 6 possible arrangements. That makes 6 and 6.

Most critical question, in how many different ways could the 6 awards be presented?
Each of the categories has 3 awards and can't be combined with the other so, if one is being realistic, catagory one has 3 awards and catagory two has three awards.

3 (of anything) only has 6 possible arrangements so the answer would be:
6 different ways for each category or 12 different ways for thoses 6 awards.

The performances were lousy. No awards given!

(7x6x5)+(6x5x4)= # of possibilities

The wording of the question could have been better. Regardless, I am pretty sure the intent was to compute the possible permutations, which was my answer. Otherwise, the number of participants in the two categories would not have been presented.

There are no 1rst, 2nd or 3rd place awards. Everybody gets a participation medal and complains that they had to practice too much.

There are so many ways this can be taken. Was permutation in the original question?

I hate when questions are not clear. In college I would clarify the various ways the question could be perceived, then solve for each. Drove the profs crazy.

I was on the board of a few schools in NY. I felt they were going the wrong way as far as teaching math went. In grade school, instead of providing the actual answer, they were being asked to estimate the answer. There is no estimate in math. There is one correct answer.

The act of holding the contest is triggering and a micro aggression. Shame on them.

So, if people who play piano don’t also play the violin so they can’t get an award for playing the violin, and people who play violin don’t also play the piano, would the answer be (9X8x7) + (7x6x5)?

567 combinations. (3 x 7 x 3 x 9)
