WebThe variance of a sum of independent random variables is the sum of the variances. Since the variance of each roll is the same, and there are three die rolls, our desired variance is 3 Var ( X 1). To calculate the variance of X 1, we calculate E ( X 1 2) − ( E ( X 1)) 2. And E ( X 1 2) = 1 6 ( 1 2 + 2 2 + ⋯ + 6 2).
