Let A and B be two sets such that n(A) = 3 and n(B) = 2.


Let A and B be two sets such that n(A) = 3 and n(B) = 2.

If (x, 1), (y, 2), (z, 1) are in A × B, find A and B, where xyz are distinct elements.


A is the set of all first entries in ordered pairs in A × B and B is the set of all second entries in ordered pairs in A × B.


n(A) = 3 and n(B) = 2

 A = {xyz} and B = {1, 2}
