This paper looks at various issues that are of interest to the sports gambler. First, an expression is obtained for the distribution of the final bankroll using fixed wagers with a specified initial bankroll. Second, fixed percentage wagers are considered where the Kelly method is extended to the case of simultaneous bets placed at various odds; a computation algorithm is presented to obtain the Kelly fractions. Finally, the paper considers the problem of determining whether a gambling system is profitable based on the historical results of bets placed at various odds.
