Question
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 TotalHigh school only 1264 1109 352 2003 4728Some college 1318 1027 1063 2554 5962Bachelor's degree 571 999 688 1225 3483Master's degree 631 757 697 1323 3408Total 3784 3892 2800 7105 17581
Solution
To find the probability that a randomly chosen adult from the town has a high school degree or some college, but no college degree, we need to add the total number of adults with a high school degree and some college, and then divide by the total number of adults.
From the table, we can see that the total number of adults with a high school degree is 4728 and the total number of adults with some college is 5962. Adding these two numbers together gives us 10690.
The total number of adults in the town is 17581.
So, the probability is 10690 / 17581 = 0.608.
Rounding to the nearest thousandth, the probability is 0.608.
