Step-by-step explanation:
Given
60 % are qualified for Job and 40 % are not
Out of qualified manager approves 70 %
out of not qualified manager approves 30 %
Total no of approved people![=0.6\times 0.7+0.4\times 0.3=0.54](https://tex.z-dn.net/?f=%3D0.6%5Ctimes%200.7%2B0.4%5Ctimes%200.3%3D0.54)
Probability of qualified and Approved by manager![=0.6\times 0.7=0.42](https://tex.z-dn.net/?f=%3D0.6%5Ctimes%200.7%3D0.42)
P(person is qualified if he or she was approved by the manager)![=\frac{0.42}{0.54}=0.778](https://tex.z-dn.net/?f=%3D%5Cfrac%7B0.42%7D%7B0.54%7D%3D0.778)
