Question
The following table represents the highest educational attainment of all adult residents in a certain town. If a resident who has only completed some college is chosen at random, what is the probability that they are aged 50 or over? Round your answer to the nearest thousandth.Age 20-29 Age 30-39 Age 40-49 Age 50 & over TotalHigh school only 442 758 1058 1269 3527Some college 622 471 985 2558 4636Bachelor's degree 1792 812 894 1820 5318Master's degree 643 526 536 841 2546Total 3499 2567 3473 6488 16027
Solution
To find the probability that a resident who has only completed some college is aged 50 or over, we need to divide the number of residents aged 50 & over who have completed some college by the total number of residents who have completed some college.
From the table, we can see that the number of residents aged 50 & over who have completed some college is 2558. The total number of residents who have completed some college is 4636.
So, the probability is 2558 / 4636 = 0.5518
Rounding to the nearest thousandth, the probability is 0.552.
