The chocolate factory classifies its candies as caramels (5 types), chocolate (7 types), and dark chocolate (10 types). A customer has ordered an assortment to consist of 4 types of caramels, 5 types of chocolate, and 7 types of dark chocolates. How many such assortments are possible?

Can I assume duplicates are allowed in the assortment? For example, if there are four types of caramels in the assortment, can any of them be the same types? The problem is a lot easier if duplicates are allowed.

There are 5 types of caramel, and thus there are 5^4 possible combinations of four.

Likewise, there are 7 types of chocolate, and thus 7^5 possible combinations of five.

And 10 types of dk choc, and thus 10^7 possible combinations of seven.

The total number of possible combinations in the assortment, then, is

(5^4)(7^5)(10^7)

which is a whole bunch.
