G. Rubin Thomas is an independent research mathematician in Combinatorial mathematics – the math behind lotto games. In the book, Against All Odds, he answers math questions on lotto. Here are a few: Why there is no strategy to win a lotto jackpot, how to minimize losses while you chase the jackpot, how to pick the least expensive blocks of numbers if you choose to play several blocks, and how to compute the combined chances of any list of numbers.
The book is most useful if you play several blocks of numbers in a lotto draw. Technical notes have been named as Appendix. The appendices numbered 4 and higher are useful in lottery play and require no mathematical knowledge or sophistication. The book is your complete lotto manual.
