discrete valued random variable

例句：

1. 1. In probability theory, a discrete valued random variable is used to represent the outcome of an experiment with only a finite number of possible outcomes.
   在概率理论中，离散值随机变量用于表示只有有限可能结果的实验的结果。
2. 2. The discrete valued random variable X can be modeled as a binomial distribution with parameters nand p, where n is the number of trials and p is the probability of success on each trial.
   离散值随机变量X可以建模为二项分布，参数n和p，其中n是试验次数，p是每次试验成功的概率。
3. 3.The discrete valued random variable Y is defined as the sum of two independent random variables Z and W, where Z and W are both discrete valued random variables.
   离散值随机变量Y定义为两个独立随机变量Z和W的和，其中Z和W都是离散值随机变量。
