Answer
A. about 93%
Step-by-step explanation
Events
• A: a student takes Japanese
,
• B: a student is in the anime club
We need to find the probability that a student takes Japanese given that he or she is in the anime club, that is, P(A|B). This probability is calculated as follows:
[tex]P(A|B)=\frac{P(A\text{ }and\text{ }B)}{P(B)}[/tex]
From the table, the probability that a student takes Japanese and is in the anime club is P(A and B) = 0.13. And the probability that a student is in the anime club is P(B) = 0.14. Therefore,
[tex]\begin{gathered} P(A|B)=\frac{0.13}{0.14} \\ P(A|B)\approx0.93\text{ or }93\text{ \%} \end{gathered}[/tex]
