According to a recent report, 60% of U.S. college graduates cannot find a full time job in their chosen profession. Assume 57% of the college graduates who cannot find a job are female and that 39% of the college graduates who can find a job are female. Given a male college graduate, find the probability he can find a full time job in his chosen profession?

Answer:

The value is
P(Z''| M) = 0.4860

Explanation:

From the question we are told that

The proportion that can not find a full time job in their chosen profession is


P(Z) = 0.60

The proportion that can not find a full time job in their chosen profession who are female is
P(F|Z) = 0.57

The proportion that can find a full time job in their chosen profession who are female is
P(F|Z'') = 0.39

The proportion that cannot find a full time job in their chosen profession who are male is
P(M|Z) = 1 - 0.57 = 0.43

The proportion that can find a full time job in their chosen profession who are male is
P(M|Z'') = 1- 0.39 = 0.61

The proportion that can find a full time job in their chosen profession is


P(Z'') = 1- 0.60 = 0.4

Generally the probability that the college graduates is a male is mathematically evaluated using Bayes' Rule as follows


P(M) = P(Z ) * P(MI Z) + P(Z'') * P(M|Z'')


P(M) = 0.6 * 0.43 + 0.4 * 0.61


P(M) = 0.502

Generally the probability he can find a full time job in his chosen profession is mathematically evaluated using Bayes' Rule as follows


P(Z''| M) = (P(Z'') * P(M|Z''))/(P(M))


P(Z''| M) =  (0.4 * 0.61)/(0.502)


P(Z''| M) = 0.4860
