TY - JOUR SN - 0021-9002 N2 - An urn contains black and red balls. Let Zn be the proportion of black balls at time n and 0?LL, then bn is replaced together with a random number Rn of red balls. Otherwise, no additional balls are added, and bn alone is replaced. In this paper we assume that Rn=Bn. Then, under mild conditions, it is shown that Zn?a.s.Z for some random variable Z, and Dn??n(Zn-Z)?
