An ice cream parlor in a remote island has 14 different flavors of ice creams: A, B, C, D, E, F, G, H, I, J, K, L, M, N.
John, who is a visitor, has a choice of 4 different types of cones: W, X, Y, Z.
(a) How many distinct 3-scoop cones can he order?
(b) How many distinct 4-scoop cones can he order?
Notes:
(i) A given 3-scoop cone may contain one or more flavors. For example, in a given cone A-A-B (top to bottom) is a valid combination.
(ii) All permutations of a given 3-scoop cone combination are deemed the same. For example, in a given cone, A-B-C and A-C-B are treated as the same combination.
(iii) The same logic in terms of (i) and (ii) is applicable in case of 4-scoop cones.
