Combination question

[pliant temple]

Can anyone explain why this solution worked?
In how many ways can 5 pets chosen from 8 dogs, 6 cats and 7 bunnies if it must be at least 2 dogs?

(8c2)(13c3) + (8c3)(13c2) + (8c4)(13c1) + (8c5) = 13342

The terms are separated by how many dogs are chosen.

The distinction between cats and bunnies didn't actually matter, so we can lump then together.

Oh, all of this assumes that the dogs, cats, and bunnies are all distinct.
