Answer 2

There are subsets of a set where “n” is the number of elements. The set A has 6 elements and so there are or 64 subsets of A. Since one of the possible subsets of A is A itself ( {1,2,3,4,5,6} is a subset of A} and A is not a proper subset of itself, we have that there are 63 proper subsets of A.
