A = {a, b, p}, B = {2, 3}, C = {p, q, r, s} then n[(A ∪ C) x B] is (1) 8(2) 20 (3) 12 (4) 16

Answer»

(3) 12

A = {a, b, p}, B = {2, 3}, C = {p, q, r, s}

n (A ∪ C) x B

A ∪ C = {a, b, p, q, r, s}

(A ∪ C) x B = {a, 2), (a, 3), (b, 2), (b, 3), (p, 2), (p, 3), (q, 2), (q, 3), (r, 2), (r, 3), (s, 2), (s, 3)}

n [(A ∪ C) x B] = 12
