Thanks both pmrw3 and bpet for the replies. I think what bpet had is essentially the answer. In addition, does anyone know if there is limiting result? For example, how Z scales when n -> infnity or when n,m -> infnity with fixed ratio m/n. Thank you.

Thanks pmrw3. But, I should have added that X_i is positive r.v. only.

Hello, I have some question about probabilistic combinatorial maximization as follows: Let X = {X_1, ..., X_n} be a set of i.i.d. positive random variables, S = {s_i} be a set of all combinations of selecting m r.v.'s from X, and Y(s_i) = the sum of r.v.'s in the combination s_i ...
