The solution:

Given:

Required:

To find the probability that a student selected at random is a senior.


\begin{gathered} P(Seniors)=\frac{number\text{ of seniors}}{total\text{ number of students}}=(5)/(30)=(1)/(6) \\ \\ Converting\text{ to percent, we multiply by 100.} \\ \\ =(1)/(6)*100=16.667\approx17\text{\%} \end{gathered}

Therefore, the correct answer is 17%
