Explanation / Answer

Number of men and women enrolled in degree-granting institutions in a certain year = Number of men enrolled in degree-granting institutions in a certain year + Number of men enrolled in degree-granting institutions in a certain year = 2777 + 4190 = 6967

Probability of selecting a female = Number of women(Female) enrolled in degree-granting institutions in a certain year / Number of men and women enrolled in degree-granting institutions in a certain year = 4190 / 6967 = 0.601

Probability of selecting a female =0.601
