Solution
To solve this problem, we first need to identify the total number of residents aged 30-39 and the number of those who have completed only high school or some college.
From the table, we can see that the total number of residents aged 30-39 is 3888.
The number of residents aged 30-39 who have completed only high school is 1033, and the number who have completed some college is 798.
So, the total number of residents aged 30-39 who have completed only high school or some college is 1033 + 798 = 1831.
The probability of a resident aged 30-39 having completed only high school or some college is therefore 1831 / 3888 = 0.471.
Rounding to the nearest thousandth, the probability is 0.471.
