Prove the following statement. Assume that all sets are subsets of a universal set U. For all sets A and B, if Ac ⊆ B then A ∪ B = U. Hint: Once you have assumed that A and B are any sets with Ac ⊆ B, which of the following must you show to be true in order to deduce the set equality in the conclusion of the given statement? (Select all that apply.) A ∩ B ⊆ U U ⊆ A ∪ B A ∪ B ⊆ U U ⊆ A ∩ B
