12. An ice-cream store has 31 flavours of ice cream and three types of cones (waffle, sugar, and plain). a) Determine the number of possible single-scoop ice-cream cones. b) How many two-scoop ice-cream cones are possible if waffle-chocolate- strawberry is considered different from waffle-strawberry-chocolate? Hint: You could have two scoops of the same flavour if you desired. c) How many two-scoop cones are possible if both flavours of ice cream must be different? Explain your reasoning.
