Question

Let set A = {1, 2, 3}, set B = {2, 3, 4}, set C = {4, 5}. Find (A ∩ B) $\times$ C.

• A. {(2, 4), (2, 5), (3, 4), (3, 5)}
• B. {(4, 2), (5, 2), (4, 3), (5, 3)}
• C. {(1, 2), (1, 3), (2, 3), (2, 4)}
• D. {(2, 3), (2, 4), (3, 5), (3, 4)}

Answer 1

The correct option is A

{(2, 4), (2, 5), (3, 4), (3, 5)}

A $\cap$ B = common elements between set A and set B= {2, 3}

C = {4, 5}

(A $\cap$ B) $\times$ C = {(2, 4), (2, 5), (3, 4), (3, 5)}
