在统计学及概率理论中，离散型均匀分布是一个离散型概率分布，其中有限个数值拥有相同的概率。

In probability theory and statistics, the discrete uniform distribution is a symmetric probability distribution whereby a finite number of values are equally likely to be observed; every one of n values has equal probability 1/n. Another way of saying "discrete uniform distribution" would be "a known, finite number of outcomes equally likely to happen".
