³ Problem

An ice cream store advertises that it makes 25 flavors of

home made ice cream. You like to order three different flavors

in a dish. How many combinations of ice cream can you test

over a very hot summer?

You can choose from 2300 dishes with different combinations

of flavors! If a long hot summer is about 90 days long, you will

need to eat about 25 ice cream dishes each day!
