A drawer contains four red socks and two blue socks. Three socks are drawn from the drawer without replacement.(adsbygoogle = window.adsbygoogle || []).push({});

a)Create a probability distribution in which the random variable represents the number of red socks.

b)Determine the expected number of red socks if three are drawn from the drawer without replacement.

Ok i need help with a).

This is what i did.

C(6,3) = 40 which is the total.

Now for since there are only two blue socks you have to draw atleast 1 red for 0 red socks.

C(4,1) x C(2,2)

I dont know if i did that right because it says without replacement. So how do i take into account that it is done without replacement.
