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 985 1201 785 1410 4381Some college 1270 1298 1356 2498 6422Bachelor's degree 646 1715 1315 1653 5329Master's degree 500 549 772 1350 3171Total 3401 4763 4228 6911 19303

To find the probability that a randomly chosen adult from the town has a high school degree or some college but no college degree, follow these steps:

1. Identify the relevant categories: We need to consider adults with "High school only" and "Some college" education levels.

2. Sum the frequencies of these categories:

   • High school only: 4381
   • Some college: 6422

   Total for these categories = 4381 + 6422 = 10803

3. Find the total number of adults: The total number of adults in the town is given as 19303.

4. Calculate the probability: $\text{Probability} = \frac{\text{Number of adults with high school only or some college}}{\text{Total number of adults}} = \frac{10803}{19303}$

5. Perform the division: $\frac{10803}{19303} \approx 0.559$

6. Round to the nearest thousandth: The probability rounded to the nearest thousandth is 0.559.

Therefore, the probability that a randomly chosen adult from the town has a high school degree or some college but no college degree is approximately 0.559.

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 follow these steps:

2. Sum the frequencies of these categories:

   • High school only: 4381
   • Some college: 6422

3. Calculate the total number of adults: The total number of adults is given as 19303.

4. Add the frequencies of the relevant categories: $4381 + 6422 = 10803$

5. Calculate the probability: $\text{Probability} = \frac{\text{Number of adults with high school only or some college}}{\text{Total number of adults}} = \frac{10803}{19303}$

6. Perform the division and round to the nearest thousandth: $\frac{10803}{19303} \approx 0.560$

Therefore, the probability that a randomly chosen adult from the town has a high school degree or some college but no college degree is approximately 0.560.
