Consider the discrete uniform distribution with density fx(x; ) = 1/(n + 1), where n is an integer, x = 0,1,2,...,n. Derive E(X) and Var(X);

Consider the discrete uniform distribution with density fx(x; θ) = 1/(n + 1), where

n is an integer, x = 0,1,2,...,n. Derive E(X) and Var(X); note that ok (n+1)/2, ok = n (2n+1)(n+1)/6. =
