following: P(A) = {x | x⊆A} This reads as, P(A) is x such that x is a subset of set A. Essentially the power set contains all the possible subsets of a given set. Remember that the empty set is a subset of ANY given set. Here is an example of a power set: let A = {a, b, c} P(A) = {Ø, {a}, {b}, {c},
