Classical Computation of Infinite Sums

The computation of the infinite sums $\sum_{k=1}^\infty \binom{k}{p} q^k = q^p/\left(1-q\right)^{p+1}$ is a classical result in probability theory. This result has far-reaching implications in various fields, including statistics, engineering, and finance.

Probability Theory

The infinite sum $\sum_{k=1}^\infty \binom{k}{p} q^k$ arises in probability theory when considering the distribution of random variables. Specifically, it appears in the study of binomial distributions, which model the number of successes in a fixed number of independent trials.

Statistics

In statistics, the infinite sum $\sum_{k=1}^\infty \binom{k}{p} q^k$ is used to compute the probability of observing a certain number of successes in a sequence of independent trials. This result has applications in hypothesis testing, confidence intervals, and regression analysis.
