The table below shows the highest educational attainment of all adult residents in a specific town. It is organized by age group and education level:| Education Level | Age 20-29 | Age 30-39 | Age 40-49 | Age 50 & over | Total ||------------------------|-----------|-----------|-----------|---------------|--------|| High school only | 1634 | 1411 | 917 | 936 | 4898 || Some college | 1946 | 1303 | 785 | 1176 | 5210 || Bachelor’s degree | 1295 | 1536 | 777 | 1980 | 5588 || Master’s degree | 818 | 949 | 195 | 792 | 2754 || **Total** | 5693 | 5199 | 2674 | 4884 | **18450** |**Question:** If a resident who is 40 or older is chosen at random, what is the probability that they have only completed high school? Round your answer to the nearest thousandth.**Solution Explanation:**1. **Determine the Total Number of Residents Aged 40 or Older:** - Age 40-49: 2674 residents - Age 50 & over: 4884 residents - Total = 2674 + 4884 = 7558 residents2. **Determine the Number of Residents Aged 40 or Older with Only High School Education:** - Age 40-49: 917 residents - Age 50 & over: 936 residents - Total = 917 + 936 = 1853 residents3. **Calculate the Probability:** \[ \text{Probability} = \frac{\text{Number with High School Education Only}}{\text{Total Number Aged 40 or Older}} = \frac{1853}{7558} \approx 0.245 \]The probability that a randomly chosen resident who is 40 or older has only completed high school is approximately 0.245.
