Question

If a student is selected at random find the probability the student is a junior

Answer 1

We need to find the probability that a student, selected at random, is a junior.

In order to do so, we can divide the total of students that are junior to the total of students in that class.

We have:

`\begin{gathered} \text{total of juniors: }2+6=8 \\ \\ \text{total of students: }4+3+6+4+2+6+2+3=30 \end{gathered}`

Thus, that probability P(junior) is:

`P(junior)=(8)/(30)\cong0.27=(27)/(100)=27\%`

Therefore, approximately 27% of the students in that class are junior students.
