Question

Given the following sets: S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, Even numbers A = {2, 4, 6, 8, 10}; Odd number B = {3, 5, 7, 9}; Natural numbers N = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} and Prime numbers C = {2, 3, 5, 7} Find the following: a) A ∪ C b) A ∩ N c) A ’ d) B ∩ N e) B ∪ N f) C ’ g) N ’ h) B ’ i) A ∪ B 2. Given U = {15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25} A = {16, 18, 20, 22} B = {17, 19, 20, 23, 24} a) Find A′∩ B′
