Answer 1

Given that, a resident who has completed only a bachelor's degree

is chosen at random.

To find the probability that a resident who has completed only a bachelor's degree are aged 50 and above.

Number of students who has completed only a bachelor's degree and are aged 50 and above =1933

Total number of students who have completed bachelor's degree is 4139.

Probability is defined as,

$P=\frac{\text{Desired outcomes}}{\text{total outcomes}}$$\begin{gathered} P=\frac{1933}{4139} \\ =0.4670 \end{gathered}$

So, the probability that a resident who has completed only a bachelor's degree are aged 50 and above is 0.4670
