Would part A just be C(12,7)? Where 12 is how many croissants you can choose from and 7 is how many types of croissants there are to choose from?
Wouldn't it be C(12,6) with repetition since there's 6 different type of croissants and after you choose one you can choose it again if you want to.
Yeah nevermind, I mean't C(12,6).
For part C, how could you compensate for counting "at least 2 of each croissant"?
