Proper subset: Set B is a proper subset of set A, if there exists an element in A that does not belong to B. 2^N where N is the number of elements in the given set gives the number of all the subsets of the given set which includes, of course, the set itself. x���P(�� �� There are 4 subsets of a set with two elements. e.g. 715+286+78+13+1=1093 subsets.

The remaining 7 subsets are proper subsets. Subsets A set with N elements has 2N subsets. Powersets: The power set is the set of all subsets of a given set. Then, the number of subsets is = 23 = 8 The subsets are {a}, {b}, {c}, {a, b}, {a, c}, {b, c}, {a, b, c}, { } In the above list of subsets, the subset {a , b, c} is equal to the given set A. it will have 127 proper subsets because subset having all the seven elements will be improper subset...and proper subset means "A set consisting of all the elements of a set except atleast one element of that set" therefore the last subset wouldn't be a proper subset.
