So I will assume you want me to do this without any formulas?

Let me do the first one.

Let us call the possible pizzas A,B,C,D,E instead to make it easier to type.

Then below are all the possible ways to put 3 together:

Code:

A,B,C
A,B,D
A,B,E
A,C,D
A,C,E
A,D,E
B,C,D
B,C,E
B,D,E
C,D,E

So there are a total of 10 different ways to do this.
