👉 In mathematics, the power set of a set S is the set of all subsets of S. It contains every possible subset of S and includes its empty set as well. For example, consider the set {1, 2, 3}. The power set of this set would be: - Empty Set: {} (since there's no element in it) - {1} (with one element) - {2} (with two elements) - {3} (with three elements)
