Topic: Permutations & Combinations

Given that;

The firm wants to randomly select 3 employees.

The total number of employees = 10

When the firm wants to select any 3 random employees from a total of 10 employees, the possible combinations of the selection can be $10C_{3}$.

So, the firm can select 3 employees in $10C_{3}$ ways

                                            = (10 x 9 x 8) / (3 x 2 x 1)

                                            = 120 ways
