Use the element method for proving that a set equals the empty set to prove following the statement. (Assume that all sets are subsets of a universal set U.) For all sets A, B, and C, if A ⊆ B and B ∩ C = ∅ then A ∩ C = ∅. Proof by contradiction: Consider the sentences in the following scrambled list.
