The power set P(A) is the set of what?
Answer and explanation
Correct answer: All subsets of A
By definition, the power set P(A) is the collection whose elements are all subsets of A. It always contains the empty set and A itself, and it also contains every other possible subset. If A has n elements, P(A) has 2ⁿ elements. It is important not to confuse an element of A, such as a, with a subset of A, such as {a}.
