Question

Let U = {q, r, s, t, u, v, w, x, y, z}
A = {q, s, u, w, y}
B = {q, s, y, z}
C = {v, w, x, y, z}.

Determine the following.

A' ∪ B

A. {q, s, t, u, v, w, x, y}

B. {r, s, t, u, v, w, x, z}

C. {q, r, s, t, v, x, y, z}

D. {s, u, w}

I think this one is C? :(

Answer 1

U = {q, r, s, t, u, v, w, x, y, z}
A = {q, s, u, w, y}
=> A' = { r, t, x, z}
B = {q, s, y, z}

A' ∪ B = {q, r, s, t, v, x, y, z}
