Understanding Lotto Math: Volume 4 Draws Without Replacement Two Drawing Machines

The chances of matching the twenty numbers drawn in a keno game are 1 in 3,535,316,142,212,180,000. That is 1 in 3,535,316 trillion! The number in itself is hard to imagine. Keno is a type of lottery, and as such, it is ruled by the laws of probability. Lotteries are played in many countries around the world, and millions of people buy tickets on a regular or occasional basis with the hope of beating the odds—even if the chances are 1 in 3.5 quintillion. But how many of those dreamers have a real understanding of the mathematical principles ruling their chances? In the following pages you will find the basic information needed to clearly understand chance in terms of easy mathematical rules, and will learn how to apply this knowledge to work out your chances of winning a prize in any lottery or lottery-like game of chance. This work is addressed not only to high school students with a passion for the mathematics of chance and probability, but also to those who simply want to understand how lotteries work in terms of mathematics. It is not going to be an in-depth study of the subject, but rather an introduction to basic concepts and methods in probability, as well as how to apply them to lotteries. This book is not promising you any secret or system to win the lottery. If there were a systematic way of predicting a winning combination, the numerous authors of the large amount of books on lottery systems would now be millionaires themselves and would not be selling the secret.
