Vedclass · Answer

(A) Given that $(1, 3), (2, 5), (3, 3) \in A 	imes B$. From these ordered pairs,the elements of set $A$ are the first components: $A = \{1, 2, 3\}$. The elements of set $B$ are the second components: $B = \{3, 5\}$. The total number of elements in $A 	imes B$ is $n(A) 	imes n(B) = 3 	imes 2 = 6$. The complete set $A 	imes B$ is $\{(1, 3), (1, 5), (2, 3), (2, 5), (3, 3), (3, 5)\}$. We are given three elements: $(1, 3), (2, 5), (3, 3)$. The remaining elements are $\{(1, 5), (2, 3), (3, 5)\}$. Thus,the correct option is $A$.

If $(1, 3), (2, 5)$ and $(3, 3)$ are three elements of $A \times B$ and the total number of elements in $A \times B$ is $6$,then the remaining elements of $A \times B$ are
