 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.
