If one employees is chosen, what is the probability this employee doesn't has an advanced degree and is female?

Question

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?

Answer 1

Number of female employees = 36
Number of female employees without advanced degree = 36×(7/10)
Probability that any random chosen employee is female and has no advances degree = 36×(7/10)×(1/180)
= 7/50
= 14%.
