Given:
See attachment for graph
Required:
If a students at random, find the probability the students the student is a senior
Explanation:
To do this , we calculate the total students
Total=4+6+2+2+3+4+6+3
Total=30
next select the value in the cell that intersects senior
male + female=2+3=5
Hence, the probability is
[tex]\begin{gathered} Pr=\frac{senior}{total} \\ \\ Pr=\frac{5}{30} \\ \\ Pr=0.3333 \end{gathered}[/tex]
Express as percentage
[tex]\begin{gathered} Pr=0.3333\times100\% \\ Pr=33\% \end{gathered}[/tex]
Required answer:
30%
