ok i think i got it
cumulative distribution function is the integral from 0 to k of a probability distribution function of k
thats why the p(k) =F(k)-F(k-1)
My statistics professor wanted me to remember an infinite series sum, but i can't remember what it was
i think it was either ( E(1/n^2) 1 to infinite ) or ( E(1/(L+n^2)) 0 to infinite ) or ( E(a^n) 0 to infinite where n is between 0 and 1)
i think it was the 2nd one, does anyone know how to...
