Given : The salaries of 150 employees in an office
An employee selected at random.
To Find : the probability that his salary is Rs. 6000 or more but less than Rs. 12000
Solution:
Salary Number of Employees
3000 - 6000 52
6000 - 9000 35
9000 - 12000 29
12000 - 15000 26
15000 -above 8
Total 150
salary is Rs. 6000 or more but less than Rs. 12000
Means salary is either 6000 - 9000 or 9000 - 12000
6000 - 9000 there are 35 employees
9000 - 12000 there are 29 employees
Hence salary is Rs. 6000 or more but less than Rs. 12000 = 35 + 29
= 64 employees
probability that his salary is Rs. 6000 or more but less than Rs. 12000
= 64/150
= 32/75
= 0.4267
