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