Answer

Explanation:

Step1: Identify relevant numbers

We want the probability of a resident aged 50 or over given they have completed some college. The number of residents who have completed some college and are aged 50 or over is 1604, and the total number of residents who have completed some college is 6551.

Step2: Calculate probability

The probability $P$ is given by the formula $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P = \frac{1604}{6551}$. $P=\frac{1604}{6551}\approx 0.245$.

Answer:

0.245
