U = {1, 2, 3, 4, 5, 6, 7, 8, 9}, A = {2, 4, 6, 8} and B = {2, 3, 5, 7} (i) A υ B = {2, 3, 4, 5, 6, 7, 8} We know that the complement of a set A is denoted by A' and it is equal to U - A, where U is the universal set. Thus, ( A υ B)' = U - ( A υ B) = {1, 9} .....(1) A' = U - A = {1, 3, 5, 7, 9} B' = U - B = {1, 4, 6, 8, 9}
