imagine you are the owner of a pizza shop. That offers three different types of crust, seven different toppings and three different cheese.
I NEED TO KNOW HOW MANY DIFFERENT COMBINATIONS THERE ARE/HOW TO GET THE ANSWER.
i don't want the answer i just want to know how to find the answer of how many combinations there are.

Best ResponseYou've already chosen the best response.1If one of each type is allowed (1 crust, 1 cheese, 1 topping), then \[\large \text{Answer} = \begin{pmatrix} \text{Number}\\ \text{of}\\ \text{Crusts} \end{pmatrix} \times \begin{pmatrix} \text{Number}\\ \text{of}\\ \text{Cheeses} \end{pmatrix} \times \begin{pmatrix} \text{Number}\\ \text{of}\\ \text{Toppings} \end{pmatrix} \] I'm using the counting principle http://www.mathsisfun.com/data/basiccountingprinciple.html
