Think of all the ways that a combination result could be useful. Remember that, in the meaning of combination, and in real card play, the order of the cards doesn't matter - the set. It's my hope that this article will inspire curiosity about the topics and the computation methods as well.Ĭombination (order doesn't matter) ( definition) Permutation (order does matter) ( definition)

Statistics and probability are interesting subjects with many practical applications, well worth studying. If you see too few equations for your taste in the first section, don't worry - just read on. This article is partitioned into two themes: applications of probability theory, followed by an exposition of the mathematical methods and algorithm design. The reason is usually naive algorithm design, an issue I explore below. By including interactive calculators that actually work, and an in-depth mathematical exposition, this article plans to remedy both problems.Īs to this article having calculators that actually work, while preparing this piece I surveyed online statistics and probability calculators, and discovered that most of them fail when presented with anything but small numbers, a crippling limitation. The reason? People tend to be unfamiliar with probability ideas, and probability results are rather inaccessible. Everyday life is filled with possible applications for probability theory, but few are exploited.
