I have two jointly normal variables X and Y with mean both zeros and variances $\sigma^2_{X}$ and $\sigma^2_{Y}$ separately, the covariance is $\sigma_{XY}$. Now I want to calculate the expected value of $Z=X*Y^{2}$, $E(Z)$. Any ideas?

Thanks.

Expected values of (X*Y^2) when X and Y are dependent normally distributed RVs
