To calculate the SD of this, use E(x^2) - [E(X)]^2, this will be the variance and just take the square root of it to get the S.D E[X] you already calculated, Now calculate E(x^2) = 115^2 *0.1 + 120^2 *0.1 and so on..

Dear Sir, I have facing a doubt in portfolio question, Sir In this question if we not calculated H.P.Y and calculate the question with figures then expected return toh shi aa rhai but standard deviation shi nhi aa rha. Sir please help me to clarify the doubt. Thank u sir.
