Question

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

Answer 1

Given: 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 × B) = {(x, y): x∈A and y∈B} 

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