Probability - A Beginner's Guide To Permutations And Combinations: The Classic Equations, Better Explained

#ad - However after taking a programming challenge for a large tech company recently, and the simple equations simply are not sufficient, challenging permutation & combination problems frequently appear, a deeper understanding is necessary. Consequently this book also devotes a large section to an example permutation problem of the kind that you might find in a programming challenge.

Permutations and combinations – better ExplainedThis book gives examples of how to understand using permutations and combinations, which are a central part of many probability problems. Those problems are frequently in programming challenges because permutations are an easy way to ensure that naïve brute force solutions can’t solve the problems in a reasonable amount of time, and that a more elegant understanding of the math is required.

Probability - A Beginner's Guide To Permutations And Combinations: The Classic Equations, Better Explained #ad - . This book walks through how that problem would be solved, and it turns out to be relatively simple and intuitive. Feedback from early reviewersSeveral of the early reviewers expressed an interest in having a longer book, and a wider variety of examples. Consequently in this version i have added examples for how combinations & permutations relate to the lottery, the odds of getting a flush in Texas Hold'em, the traveling salesperson problem, the classic urn problems, as well as the binomial theorem.

The focus of this book is on understanding why the permutation and combination equations are what they are, which ends up making them a lot easier to understand, remember, and expand than simply memorizing the equations. Permutations and combinations is a subject usually makes up a chapter in most statistics text books, but it is a chapter that doesn’t do the subject its proper justice.

A big thank you for those suggestions!what motivated This Book?I learned the permutation and combination equations in an early college math class, and have used them over the years and never had reason to revisit them looking for a deeper understanding.
