n. 1. (Mathematics) maths. a. a set the members of which are all members of some given class: A is a subset of B is usually written AâB. b. proper subset one that is strictly contained within a larger class and excludes some of its members.
Therefore, number of all possible subsets of A is 8 which is equal 2\(^{3}\). Proper subsets are = { }, {1}, {3}, {5}, {1, 3}, {3, 5}. Number of proper subsets are 7 = 8 - 1 = 2\(^{3}\) - 1. 2. If the number of elements in a set is 2, find the number of subsets and proper subsets.
