Question:
Given, A = {2, 3, 5} and B = {0, 1}. Find the number of different ordered pairs in which the first entry is an element of A and the second is an element of B.
Solution:
This is the example of Cartesian product of two sets.
The pairs in which the first entry is an element of A and the second is an element of B are :
$(2,0),(2,1),(3,0),(3,1),(5,0),(5,1)$
$\Rightarrow 3 \times 2=6$
