Hints: This problem has all the information you need, but not in the typical ready-to-use form. The table above can tell you the proportion of people with various levels of education in the population. Keep in mind that any degree (Associate, Bachelor, or Advanced) counts as graduating from college.

Education Employed Unemployed Not a high school graduate 0.0975 0.0080 High school graduate 0.3108 0.0128 Some college, no degree 0.1785 0.0062 Associate Degree 0.0849 0.0023 Bachelor Degree 0.1959 0.0041 Advanced Degree 0.0975 0.0015

Explanation / Answer

probability that the individual is a college graduate. 0.1959 + 0.0041 + 0.0849 + 0.0023 + 0.0975 + 0.0015

probability that the individual is a college graduate. = 0.3862
