In a certain corporation, there are 144 male employees and 36 female employees.  It is known that 10% of the male employees have advanced degrees and 30% of the females have advanced degrees.  If one of the employees is chosen at random, what is the probability this employee doesn't has an advanced degree and is female?

OPtion

1) 03/25
2) 04/25
3) 06/25
4) 03/50
5) 01/50
6) 0.7/50
7) 9/50
8) 11/50
9) 07/50
10) None of these

Solution

Total number of employees = 144+36 = 180

Number of female employees = 36
Number of female employees without advance degree = 70*36/100 = 126/5

Probability = 126/5*180 = 14/5*20 = 7/50
