## A -Statistical extension of the Korovkin type approximation by Erkus E., Duman O.

By Erkus E., Duman O.

During this paper, utilizing the idea that ofA-statistical convergence that is a regular(non-matrix) summability strategy, we receive a normal Korovkin sort approximation theorem which matters the matter of approximating a functionality f through a chain {Lnf } of optimistic linear operators.

1), the sample space S1 consists of eight S1 = {HHH, ... , TTT}. v. giving the number of heads obtained, find (a) In the experiment of tossing a fair coin three times (Prob. equally likely sample points P(X=2); (b) P(X< 2). (a) Let AC S1 be the event defined by X= 2. Then, from Prob. 1, we have A = (X= 2) = {l;: X(l;) = 2} = {HHT, HTH, THH} Since the sample points are equally likely, we have 3 P(X=2)=P(A)=8 (b) Let BC S1 be the event defined by X< 2. 3 A. v. X is determined by the behavior of Fx(x).

5), S nB=B. 55), P[(A1 UA2)nB] P(AI UA2 IB)= P(B) Now by Eqs. 17), we have and AI nAz = 0 impliesthat (AI n B) n (Az nB) = 0. 44. Find P(A I B) if (a) An B = 0, (b) A c B, and (c) B c A. (a) IfAn B= 0,thenP(An B) = P(0) = 0. 45. Show that if P(A I B)> P(A), then P(B I A)> P(B). �IB )=P(AnB) >P(A), thenP(An' B)>P(A)P(B). 46. B) By Eqs. 7), we have AUA =S, Then by Eqs. 98), we get P(AUAI B)= P(SiB)=1= P(AiB) + P(AiB) Thus we obtain P(AiB)=1- P(AiB) note that Eq. 99) is similar to property 1 (Eq. 39)).
