Unions, intersections, and complements involving 3 sets Sets A, B, and C are subsets of the universal set U. These sets are defined as follows. U = { f , g, h, p, q, r, x, y, z} A = {f , g, p, q} B = { g, h, q, x, y } c= {p, q, x, y, z} Find Cn (B' U A). Write your answer in roster form or as O. cn ( B ' U A ) = 1 O 0,0,... X
