Lily Novak · Answer 1

Answer: One of them is the set {1,2,3,4,5,6}itself; one is the empty set, containing no elements. "Proper subset of a set " usually denotes a subset in which at least one element of the original set is missing; so one of the subsets - the original set iitself - is not a proper subset. Therefore the answer is 63.
