1. The problem statement, all variables and given/known data Lets say I roll 2 fair dice and take the sum of the square of each dice. What formula will be the variance? 2. Relevant equations var(x)=e(x^2)-e(x)^2 3. The attempt at a solution For dice A; E(A)=3.5 E(A^2)=91/6 ^ same for dice B. VAR(A^2+B^2)=E(A^4)-E(A^2)^2+E(B^4)-E(B^2)^2 ?
