An ice cream parlor advertises a special deal. You can get 3 scoops of ice cream for a very low price

So, it's possible to have two scoops of vanilla and one scoop of chocolate (but the order of the scoops is still not important).

If the ice cream parlor offers 27 flavors, how many different possible combinations of 3 scoops can you make, assuming that you CAN have more than one scoop of a given flavor.
