A PIZZA PARLOR HAS A CHOICE OF 13 TOPPINGS FOR ITS PIZZAS. fROM THESE 13 TOPPINGS MANY DIFFERENT 2-TOPPINGS PIZZAS CAN BE ORDERD? aSSUME THAT THE ORDER IN WHICH TOPPINGS ARE LISTED DOES NOT MATTER.

This is a simple problem in combinations. You want to select 2 toppings out of 13 available. So it's combinations of 13 things taken two at a time.
