+1836 Oh right, this is only for the first. Thanks Alan:
Since we can add expected values of independent events, the expected value of the sum is the sum of the expected values of each.
Since we are just as likely to pick x as 1-x, the expected value of x (and likewise y) is equal to 1/2.
Therefore the expected value of the sum is 1/2+1/2=1.
hi, I was the one that posted this. May you answer the other questions that came along with it please?
