Answer:The answer is $\frac{7}{18}$ and the number in green box =7

Step-by-step explanation:

P(Sophomore| Girl)=?

We have P(A | B) =P(A∩B)/ P(B)

P(Sophomore∩Girls)= $\frac{7}{30}$

Total Students =8+12+5+5 =30

Total girls =4+7+3+4 =18

P(Girls)= $\frac{18}{30}$

P(Sophomore | Girl)=P(Sophomore | Girls)/P(Girls)

= $\frac{7}{30\frac{18}{30} }$

= $\frac{7}{18}$

The number in green box =7
