Let U={r, s, t, u, v, w, x) and A={s, w}. Use the roster method to write the set A'. A'={ (Use a comma to separate answers as needed.)

U= {a, d, j, k, o, q, v} X = (a, j, o, v} Y = {a, d, j} Z = {d, j, k, o, q} Find the following set: (ZUX')'n Y Let: (ZUX')'nY= (Use a comma to separate answers as needed.) ***

Find the correct answer:

Let U = {1, 2, 3, 4, 5, 6, 7), A = {2, 4, 6, 7), and B = {1, 4, 7). Find the set (A U B)'. (AUB) = (Use ascending order. Use a comma to separate answers as needed.)
