well since i am throwing two different dice and squaring them, this means that they are independent, shouldn't I be able to use var(x+y)=var(x)+var(y)? VAR(A^2+B^2)=E(A^4)-E(A^2)^2+E(B^4)-E(B^2)^2

Homework Statement Lets say I roll 2 fair dice and take the sum of the square of each dice. What formula will be the variance? Homework Equations var(x)=e(x^2)-e(x)^2The 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 ?

Thx for the help guys.. right now I am trying to figure out part (b).Why is it bigger than 60%? Any hints?

thx Dick..

Okay. So they still play the last game even though team A won the first 2? That will give me (0.6)^3 +0.432=0.648.Am i right?

Homework Statement Two teams, teams A and B, are competing in a tournament. Suppose the tournament is a ‘best-of-3’ series; in other words, the first team to win 2 games wins the tournament. Let’s suppose that team A has a slight edge on team B, such that the probability that team A...
