The answer is option b. 384
Since 1/8 of the population is left handed, there is another 7/8 that are right handed.
Let's call x to the number of students, then:
[tex]\begin{gathered} \frac{1}{8}\cdot x=48 \\ \end{gathered}[/tex]
This means, the an eight of the total students are left handed. Now we can solve for x:
[tex]x=8\cdot48=384[/tex]
