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 ∩ C)

Answer 1

{q, s, u, w, y, z}

Answer 2

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

Answer 3

\(B\cap C\) is the set containing the elements common to both B and C.
\(A\cup (B\cap C)\) is the set containing all the elements from both A and \(B\cap C\).
