Using the sets A $ \times $ B and A $ \times $ C from part (ii) [ i.e., Now (A $ \times $ B) = {(1,3), (1,4), (2,3), (2,4), (3,3), (3,4)} and (A $ \times $ C) = {(1,4), (1,5), (1,6), (2,4), (2,5), (2,6), (3,4), (3,5), (3,6)} Therefore, (A $ \times $ B) $ \cap $ (A $ \times $ C) = {(1, 4), (2, 4), (3, 4)}. ] above, we obtain
(A $ \times $ B) $ \cup $ (A $ \times $ C) = {(1,3), (1,4), (1,5), (1,6), (2,3), (2,4), (2,5), (2,6), (3,3), (3,4), (3,5), (3,6)}.
