The following table represents the highest educational attainment of all adult residents in a certain town. If an adult is chosen randomly from the town, what is the probability that they have a high school degree or some college, but have no college degree? Round your answer to the nearest thousandth.
Age 20-29 Age 30-39 Age 40-49 Age 50 & over Total
High school only 603 958 818 1274 3653
Some college 1558 755 431 909 3653
Bachelor's degree 661 418 643 1759 3481
Master's degree 404 976 306 483 2169
Total 3226 3107 2198 4425 12956

Answer 1

P = (High school only + Some college) / Total = (3653 + 3653) / 12956 = 7306 / 12956 ≈ 0.564 (to the nearest thousandth).
