Given the universal set U = {v, w, x, y, z), and subsets A = {v, w, z} and B = {x, y, z), indicate the roster
lukranit [14]
If U = {v, w, x, y, z} and A = {v, w, z}, then
A' = {x, y}
(A' is the complement of A - it's the set containing all elements of U that are not in A)
If B = {x, y, z}, then
B' = {v, w}
Their their union is
A' U B' = {v, w, x, y}
