An ice cream shop serves 7 different flavours of ice cream: chocolate, strawberry, banana, vanilla, mango, mint, and pistachio. You have paid for a 3-scoop bowl of ice cream. Now assume that flavour repetitions are allowed (for example you can have all 3 scoops be chocolate.) How many different 3-scoop bowl variations can you have in this case?
Note: The actual arrangement of the scoops in the bowl is not important.
