Formula to find number of subsets is = 2n Substitute n = 5. = 25 = 32 Then, number of proper subsets is = 32 - 1 = 31 So, the given set A has 32 subsets and 31 proper subsets. Problem 2 : Let A = {a, e, i, o, u}. Find the number of subsets and proper subsets of A. Solution : The given set A contains 5 elements. Then, … See more Null set is a proper subset for any set which contains at least one element. For example, let us consider the set A = {1}. It has two subsets. They are { } and {1}. Here, null set is … See more A set which contains all subsets is called power set. Let us consider the set A. Then, the set which contains all the subsets of A is the power set of A. The power set of A is denoted by P(A). Cardinality of Power … See more Let us consider null set or empty set given blow. { } Here, the above null set contains zero elements. So, n = 0. Then, the number of subsets is = 20 = 1 The subset of null set is { } The … See more Problem 1 : Let A = {1, 2, 3, 4, 5}. Find the number of subsets and number of proper subsets of A.
