Answer to Question #3791 in Finance for saniya

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 A ∪ (B ∩ C)

Answer 1

B ∩ C =& {q, s, y, z} ∩{v, w, x, y, z} = {y, z}

A ∪ (B ∩ C) = {q, s, u, w, y} ∪ {y, z} = {q, s, u, w, y, z}
