1 22 1 LAW OF LARGE NUMBERS . RANDOM SERIESPROOF .let us defineFix c > 0 . For any co in the setA = {co :max ISj (w)I > E},1< j -< nv(w) = min{j : 1 < j < n, ISj(w)i > E) .Clearly v is an r.v . with domain A .PutA k = {co : v(co) = k} _ {w : max ISj(w)I < E, ISk(w)I > E1,1
5 .3 CONVERGENCE OF SERIES 1 123where the last inequality is by the mean value theorem, since I Sk I > E on A k bydefinition . The theorem now follows upon dividing the inequality above by E 2 .Theorem 5 .3 .2 . Let {Xn } be independent r .v.'s with finite means and supposethat there exists an A such that(3) Vn : IX,, - e(X n )I < A < oo .Then for every E > 0 we have(4) ~'{ max 13 j I< E} < ( + 4E)21 < j
