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!
