1) Suppose the universal set is {a, b, c, d, e, f, g, h} and A = {a, b, c, d}, B = {a, d, e}, C = {c, f, g, h}. List the element of the set (A ∪ B)' a) { a, b, c, d, e} b) { e, f, g, h} c) {f, g, h} 2) If A = {5, 6, 7} and B = {6, 8, 10, 12}. Then, A ∪ B = {5, 6, 7, 8, 10, 12} a) TRUE b) FALSE 3) If A = {1, 3, 7, 9, 10}, B = {2, 5, 7, 8, 9, 10}, C = {0, 1, 3, 10}, D = {2, 4, 6, 8, 10}, E = {negative natural numbers} and F = {0}. Find B ∪ F  a) {0, 2, 5, 7, 8, 9, 10} b) {2, 5, 7, 8, 9, 10} c) {0} 4) What is the complement of A union B ? a) {10, 11, 12, 14, 15, 18, 21} b) {12, 14, 15, 18, 21} c) {10, 11, 13, 16, 17, 19, 20} 5) In the Venn diagram, the blue region represent: a) The complement of A intersection C b) A U B U C c) The complement of B intersection C 6) What statement does the shaded region represent? a) B ∩ C ∪ A b) A ∪ B c) C' 7) From the above Venn diagram, what is the set S' ? a) {blair, francis, glen, jade} b) {casey, drew, jade, glen, blair, erin, francis, ira} c) {jade, glen, blair, erin, francis, ira} 8) If A = {2, 3, 4, 5}, B ={c, d, e, f} and C = {4, 5, 6, 7}. Find A ∪ B a) {2, 3, c, d, e, f} b) {2, 3, 4, 5, c, d, e, f} c) {2, 3, 4, 5, 6, 7}
