Problem 3 The power set of any set A is denoted by P (A) and is defined as the set of all subsets of A, including the empty set and the set A itself. Think of ⊆ as defining a relation on P (A) where P, Q ∈ P (A) are related if and only if P ⊆ Q. Is this relation reflexive, symmetric, and/or transitive?
