Question

A={a, b, p},B={2,3},C={p,q,r,s}then n[(AUC)×B]is​

Answer 1

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

Answer 2

Answer:n[(A∪C)×B]=12

Step-by-step explanation:

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

n[(A∪C)×B]=12

A∪C={a,b,p,q,r,s}

A∪C×B={(a2),(b,2),(p,2),(q,2),(r,2),(s,2),(a3),(b,3),(p,3),(q,3),(r,3),(s,3)}
