comment What is the variance E[A]^2, statistics?
Where are you stuck? FYI, $E[A]$ is a constant, so that $E[A]^2$ is a constant, so that its variance is 0. Are you sure you wrote the question correctly?

comment Who are some blind or otherwise disabled mathematicians who have made important contributions to mathematics?
Euler became blind later in life and his Wikipedia article suggests he may have sped up his productivity after that with the help of scribes.

comment Lifetime of flat panel monitor - Taking into account dimming and not just stop working
Thanks for the info but I have a follow up. How do you know the 7 year old monitor is working absolutely fine? My question is asking about things that are not obvious. You may look at a monitor and think it looks fine but you also may have eye strain and lean closer to your monitor to see, and not even know you're doing it.
