Grade 8 - Mathematics 4.13 Cartesian Product of Two Sets - III

Example:
If A = {a,b,c,d,e} and B = {5,6,7}, then find the number of ordered pairs in A X B.

Solution:
The number of elements in set A = 5
The number of elements in set B =3
The number of ordered pairs in A X B is 5 * 3 = 15.
Therefore, the number of ordered pairs in A X B is 15.

Directions: Solve the following problems. Also write at least five examples of your own.
