Question

PLEASE HELPPPP!!!!!!!

Answer 1

Answer:The answer is
`(7)/(18)` and the number in green box =7

Explanation:

P(Sophomore| Girl)=?

We have P(A | B) =P(A∩B)/ P(B)

P(Sophomore∩Girls)=
`(7)/(30)`

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

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

P(Girls)=
`(18)/(30)`

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

=
`(7)/(30(18)/(30) )`

=
`(7)/(18)`

The number in green box =7
