$A = \{1, 2, 3\}$ and $B = \{3, 8\}$, then $(A \cup B) × (A \cap B)$ is

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

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

Solution

(b) $A \cup B = \{ 1,{\rm{ 2, 3, 8}}\} $; $A \cap B = \{ 3\} $

$(A \cup B) \times (A \cap B) = \{ (1,\,3),\,(2,3),(3,3),(8,3)\} $.
