Question:

If (1, 3), (2, 5) and (3, 3) are three elements of A × B and n (A × B) = 6, then the remaining three elements of are __________.

Solution:

Given (1, 3), (2, 5) and (3, 3) ∈ A × B and n (A × B) = 6

According to given collection,

A = {1, 2, 3}    (since from (xyxA and yB )     

and B = {3, 5}

i.e   A × B = {(1, 3), (1, 5), (2, 3), (2, 5), (3, 3), (3, 5)}

 Remaining elements of A × are (1, 5) (2, 3) and (3, 5) 

i.e Remaining elements of A × are  (1, 5) (2, 3) and (3, 5)
