Hello,

is there anyone who is able to show me how solve in Mathematica the following 
problem?

I have two random variable S_i and S_j whose mean and variances are m_i, m_j 
and sigma_i and sigma_j and whose correlation is rho_ij
how can I compute ExpectedValue(S_j , S_j) and its derivative

Thanks
