ABSTRACT
The gamblers who play casino Roulette are bound to lose, since their expected earnings are less than zero. Why on Earth would anyone play? The answer is the subject of this book: statistics! More speciŸcally, the answer lies in the variability (randomness) that all statistics exhibit. While the expected earnings are negative, the actual earnings can be positive. It is the positive outcomes that excite gamblers so much. Who doesn’t enjoy a little free money? Some people attribute this free money to “good luck” or even worse, to “skill,” but you should know better by now. Your “good luck” at casino Roulette is really just “randomness going in your favor”!
