Question

Let A and B be two sets such that n(A) x B, find A and B, where x, y, z are distinct elements.

Answer 1

Given : n(A) = 3 and n(B) = 2 

To find : distinct elements of set A and B 

Also, 

It is given that, 

{(x, 1), (y, 2), (z, 1)} A × B 

Set A has 3 elements whereas.

Set B has 2 elements. 

Also, 

A × B = {(a, b): a ∈ A and b ∈ B} 

Therefore, 

A ∈ {x, y, z} and B ∈ {1, 2}
