The newly opened ice-cream parlor has an exotic smoothie-making machine. Thereare five flavors — vanilla, mango, chocolate, raspberry, and lime, and you would picktwo of those five flavors, and the smoothie will be automatically made for you (twoscopes of ice-cream will be scooped up and blended together with milk and ice). Thetwo flavors can be the same (e.g. two scopes of mango).How many different flavors can be made?

5 choices for the first scoop and 5 for the second scoop = 25 choices altogether.

This is a simple Permutation.

 

For the first choice, you have 5 options.

And As you can repeat flavours, you will again have 5 options.

 

Now you multiply that and you get:  $5^2=25$

 

Hope that helps!!! :)
