If is given that $A \times B=\{(a, x),(a, y),(b, x),(b, y)\}$

We know that the Cartesian product of two non-empty sets $P$ and $Q$ is defined as

$P \times Q=\{(p, q): p \in P, q \in Q\}$

$\therefore $  $A$ is the set of all first elements and $B$ is the set of all second elements.

Thus, $A=\{a, b\}$ and $B=\{x, y\}$
