In this summer school class there are 28 male students and 15 female students. An experiment is done that consists of selecting a student at random, and recording their gender. This is done 4 times WITH REPLACEMENT.

1) Fill in the following probability table for the number of female students drawn?

X P(x)

0

1

2

3

4

I have tried to use the binomial probability formula (* this means multiplication) P(x)=n!/(n-x)!x!*p^x*q^n-x but i don't know what the probability variable is and i'm tired of going nowhere with this. Thank you so much.
