I found a newly released roulette math book titled “Roulette Odds and Profits: The Mathematics of Complex Bets”. You can find the paperback on Amazon or a free ebook sample at http://probability.infarom.ro/books.html .
If anyone got it, I have a question regarding a term used throughout the book: it is about the “overall winning probability”. The author uses this term when he describes every particular betting system, but he does not provide a precise definition in the first part of the book (the math part). Or maybe it is obvious but I do not get it.
I would appreciate any explanation.
