Answer:

Step-by-step explanation:

Given that a small manufacturing firm has 250 employees. Fifty have been employed for less than 5 years and 125 have been with the company for over 10 years. So remaining 75 are between 5 and 10 years.

A) Probability that the selected employee has been with the firm less than 5 years = $\frac{50}{250 } \\= 0.20$
