Explanation / Answer

Dear Student Thank you for using Chegg !! U = {A , 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, J , Q , K } B = {A, 2, 5, 9, Q} C = {4, 7, 8 , 10, Q, J } D = {3, 5, 7, 10, J} a) B U C = {A, 2, 4, 5, 7, 8, 9, 10, Q, J} b) D ^ B = { 5 } c) D' = {A , 1, 2, 4, 6, 8, 9 , Q , K } C ^ D' = {7, 10, J }
