| 摘 要： | 已知若X、Y是相互独立的随机变量且服从相同参数的二项分布，则X关于X＋Y的条件分布是超几何分布；反之亦然（参见文献［1］）．本文对上述结果的逆命题的条件加以削弱，证明了该逆命题仍然成立．

| Abstract: | It is well known that if X, Y are mutually independent random rariables which subordinated to a binomial distribution with the same parameters, then the distribution is a supergeometric distribution. Moreover, the converse proposition is true. In this paper we give a proof of the converse proposition for some weak conditions. |
