Question

A grocery store employs 15 cashiers, 25 stock clerks, and 10 delivery personnel. Among them, 10 cashiers, 10 stock clerks, and 5 delivery personnel are married. If an employee is selected at random, find the probability that the employee is not married.

Answer 1

0.5 or 50%

Explanation:

The number of total employees is:

`T=15+25+10 =50\ Employees`

The number of married employees is:

`M=10+10+5 =25\ Employees`

The probability that a randomly selected employee is not married is given by:

`P=1-(M)/(T)\\P=1-(25)/(50)\\P=0.5\ or\ 50\%`

The probability is 0.5 or 50%.
