+68 Tino's Ice Cream Shoppe features seven flavors: vanilla, chocolate, pistachio, coconut, blackberry, lemon, and saffron. Tino will gladly make you an ice cream shake featuring any two scoops you want (not necessarily of different flavors). For example, you can order blackberry-vanilla, or pistachio-saffron, or even chocolate-chocolate. Since the scoops are just going into the blender anyway, the order of the scoops doesn't matter: there's no difference between blackberry-vanilla and vanilla-blackberry.
How many different shakes can you order?
