We have random variables ybar sample mean and w the sample

We have random variables: Ybar (sample mean) and W (the sample variance) for the sample size of n=2 from the distriubiton:

y 0 2 4

p(y) 0.6 0.3 0.1

We have E(Y)=1.0 V(Y)= 1.8 and V(Ybar)= 0.9

Obtain the variance of the sample variance, V(W).
