This book could be read by a willing high school student. Almost no mathematical background is needed. It could make a good companion book to a general education course in basic statistics like Math 108 or Math 160 at Parkland College.
This is a light-hearted probability and statistics book with 17 chapters and 254 pages. It covers basic probability as applied to daily lives, casinos, card games, medical studies, polls, biology, and email spam. The book is written very leisurely with frequent asides (basically short stories) that attempt to be humorous. Also covered are the Law of Large Numbers, conditional probability, and basic hypothesis testing with p-values. There are light chapters on evolution, chaos theory, and quantum mechanics.
I almost didn't finish reading this one since it starts out so slowly, trying to drill in the point that coincidences aren't all that amazing. The book takes a long time to present any math other than the probability that a particular outcome will happen is one out of the size of the sample space. Also, the humor was lost on me. I found the cute little stories to be more annoying than humorous.
However, the book was a very quick read and I did get some good information about how medical studies are conducted, about interesting uses of actual historical polls, and there was an excellent short summary of what quantum mechanics is, its history, and its key results.
Don't expect to learn much math from this book. It won't improve your grade in your statistics or probability course, but it could help give you an understanding of what it is you are learning in that course. And who knows, you might find the book amusing and delightful.
