Please prove the following with clear steps and/or related theorems. Problem 2. If X is a set, P(X) denotes the set of all subsets of X. So for example, if X = {x, y}, then P(X) is the set {Ø, {x}, {y}, {x, y}}. For subsets A and B of X, let A + B denote the set of x € X such that x is in both A and B or æ is in neither A nor B. (i) Show that (P(X), →,U) is a ring.
