I'm not so sure about that. But that's partially because the original post is hard to follow.

From the description it seems like multinomial might be more appropriate?

I'm going to agree with @hlsmith and @Dason; it is unclear what the question is actually asking. Is there some variable for which one of 5 categories may occur and you're asking what is the probability of seeing 2 of the first ,1 of the second,0 of the third, 0 of the 4th, and 17 of the 5th category?

Or are you asking something else?

My interpretation was an expanding on @Dason's idea, but if you are unsure of the question on your own, I suggest that you ask the professor the correct interpretation first (i.e. is this a single multinomial variable with 5-levels). This will help us avoid guidance that may not be correct given the true intention of the problem.
