I'm so confused--I know what each of these is, but when using a partition (for groups of non-distinct objects), can that be applied to a permutation OR combination, or JUST combination?
Well that's just it--I'm trying to find a general rule/definition.
But I think I may have solved it because I found a case of a permutation using a partition (I THINK lol):
ex. How many permutations are there of the letters of the word "greet"?
answer: 5!/2! --> where 2 is the number of non distinct items (e in this case)
