Try This 1

 

Suppose you are planning to open an ice cream stand and have 4 kinds of ice cream: chocolate, vanilla, strawberry, and tiger. You plan to serve 2 different scoops at a time. Use Two Scoops to determine how many two-flavour cones can be made.

 

1. If you wanted to advertise the number of different two-flavour cones available, would you calculate the number available by using 4P2 = 12? Explain.
2. If you added another flavour, blueberry, how many different cones could you produce?
