Subsets of a given Set. If a set contains ânâ elements, then the number of subsets of the set is 2\(^{2}\). If a set contains ânâ elements, then the number of proper subsets of the set is 2\(^{n}\) - 1. In general, number of proper subsets of a given set = 2\(^{m}\) - 1, where m is the number of elements. 1.
For each subset of R define a 1 â 1 correspondence from R to itself as follows: Since |R| + |R| = |R| it follows that we can partition R into two pairwise disjoint subsets A and B that are each in 1 â 1 correspondence with R; let f and g be 1 â 1 correspondences from R to A and B respectively.. Give examples of sets A, B, C such that each of the three pairwise intersections A (B, A (C, B (B is nonempty but the total intersection A (B (C is empty (this illustrates the importance of recognizing the difference between a disjoint collection of sets and a pairwise disjoint collection of sets).
