Let A = {1, 2} and B = {2, 3}.

Question:

Let $A=\{1,2\}$ and $B=\{2,3\} .$ Then, write down all possible subsets of $A \times B$.

 

Solution:

A = {1, 2} and B = {2, 3}

Need to write: All possible subsets of A × B

A = {1, 2} and B = {2, 3}

So, all the possible subsets of A × B are:

$(A \times B)=\left\{(x, y): x^{\in}\right.$ A and $\left.y \in_{B}\right\}$

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