Question

A company has 140 employees of whom 30 are supervisors. Seventy of the employees are married and 20% of the married employees are supervisors. If an employee of the company is randomly selected, then what is the probability that the employee is married and a supervisor ?

• A. 0.4
• B. 0.3
• C. 0.2
• D. 0.1

Answer 1

The correct option is D 0.1

Number of married employees = 70

Number of married, who are supervisors = 20% of 70

$=\frac{1}{5}\times 70=14$

Therefore, required probability = $\frac{14}{140}=0.1$
