A sequence of independent Bernoulli trials, each of which is a success with probability , is conducted. For , let be the number of trials required to obtain consecutive successes. Using techniques from elementary probability theory, we present a derivation which ultimately yields an elegant expression for the probability mass function of , and is simpler in comparison to what is found in the literature. Following this, we use our derived formula to obtain explicit closed-form expressions for the complementary cumulative distribution function and the th factorial moment of .

关于需要获得的试验次数 连续成功
一系列独立的伯努利试验,每个试验都有可能成功 进行。为了, 让 是获得所需的试验次数 连续的成功。使用基本概率论的技术,我们给出了一个推导,最终得出了概率概率函数的优雅表达。,并且与文献中的内容相比更简单。此后,我们使用派生公式为互补累积分布函数和的阶乘矩 。
