So if there are S sizes, F flavors and T Toppings to choose from, then there are
S * F * T possible combinations
For example:
S = 3 sizes (small, medium, large)
F = 4 flavours ( vanilla, chocolate, strawberry, mixed)
T = 2 toppings ( sprinkles and peanuts)
Then there are 3 * 4 * 2 = 24 possible combinations
