Question

If A = 1,2, 3 B = 3, 8 then ∴ (A ∪ B) × (A ∩ B) is equal to (A)  (3,1), (3, 2), (3, 3), (3,8)  (B)  (1,3), (2, 3), (3, 3), (8,3)  (C)  (1,2), (2, 2), (3,3), (8,8)  (D)  (8, 3), (8,2), (8,1), (8, 8)

A ∪ B = 1,2,3, 8 and A ∩ B = 3 ∴ (A ∪ B ) × (A ∩ B) = (1.3), (2, 3), (3,3), (8.3)

Q. If $A = {1, 2, 3}$ , $B = {3, 8}$ , then $∴ (A \cup B) \times (A \cap B)$ is equal to

${(3, 1), (3, 2), (3, 3), (3, 8)}$

${(1, 3), (2, 3), (3, 3), (8, 3)}$

${(1, 2), (2, 2), (3, 3), (8, 8)}$

${(8, 3), (8, 2), (8, 1), (8, 8)}$

$A \cup B = {1, 2, 3, 8}$ and $A \cap B = {3}$
$∴ (A \cup B) \times (A \cap B)$
$= {(1.3), (2, 3), (3, 3), (8.3)}$

Q. If A={1,2,3}, B={3,8}, then ∴(A∪B)×(A∩B) is equal to

{(3,1),(3,2),(3,3),(3,8)}

{(1,3),(2,3),(3,3),(8,3)}

{(1,2),(2,2),(3,3),(8,8)}

{(8,3),(8,2),(8,1),(8,8)}
