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.

**PsyDAG**, Sunday, July 10, 2011 at 2:09pmIt is just like picking 4 people without replacement.

P(0) = 28/43 * 27/42 * 26/41 * 25/40 = ?

P(1) = 15/43 * 28/42 * 27/41 * 26/40 = ?

Use a similar process for the remaining two probabilities.
