Question

Given $A=\{5,6,7\}$ and $B=\{3,4\}$. Form all possible ordered pairs and write the total number of ordered pairs formed so that the first component is from set A and second component is from set B.

What is the total number of such pairs?

Answer 1

Possible ordered pairs with first component from Set $A$ and second from set $B$ are

$(5,3),(5,4),(6,3),(6,4),(7,3),(7,4)$.

Hence, the total no. of ordered pairs formed is $6$.
