WebAug 16, 2024 · Cartesian Products. Definition 1.3. 1: Cartesian Product. Let A and B be sets. The Cartesian product of A and B, denoted by A × B, is defined as follows: A × B = { ( a, b) ∣ a ∈ A and b ∈ B }, that is, A × B is the set of all possible ordered pairs whose first component comes from A and whose second component comes from B. WebA power set is a collection of all the subsets of a set. 2n gives the total number of subsets for a set of ‘n’ items. Because the elements of a power set are subsets of a set, the cardinality of a power set is given by P (A) = 2n. In this case, n represents the total number of elements in the provided set. Example: Set A = {1,2}; n = 2. WebTo prove a set is a subset of another set, follow these steps. (1) Let x be an arbitrary element of set S. (2) Show x is an element of set T.
