Apizza place offers 5 different cheeses and 10 different toppings. in how many ways can a pizza be made with 2 cheese and 3 toppings? i cannot figure this out and i know it's so simple!

The problem makes use of the concept of combination wherein you are to x from y number of given without the regards to its order. In the given above, the number of ways can be calculated by the equation,
                                n = (5C2) x (10C3) = 1200
Therefore, a pizza place can make pizza in 1200 ways.
