I know why betting the 0-00-1-2-3 line in roulette is the worst bet mathematically you can make in roulette, but would someone tell me the odds of winning if I did the following? Bet $5 on 0-00-1-2-3 and $10 on black. As I see it, I would win something on 22/38 of the spins, or 58% of the time. But I don't know how to do the math to figure out whether those wins would be profitable or not... in other words, would I lose more money on the $10 bets than I would win on the $5 bet?

Welcome to the Forum.

If you know the 7.89% -EV bet is the worst bet at roulette why would you want to bet it in any combination? And more importantly, why would you not seek a single 0 wheel that only takes 1/2 your bet when you lose on even money wagers? The Mirage in Vegas has such a wheel (-1.31 EV) and I think the Venetian and other stores do to (not sure about other gambling destinations).

I'll answer your questions in reverse rst, I am not lucky enough to be coming to Vegas, I'm going to be playing at an Indian casino in the if I want to play roulette -- which I do-- I have no choice but to play at a double-zero (American) style table.

Now, as to why I want to bet a lousy combination... I'm not sure I do... I just want to know the math... As I see it, if the 0 or 00 came up, I would win $30, less the $10 bet on black; if the 1 or 3 came up, I would win $30 less the $10 bet on black; if the 2 came up, I would win $30 + $10 cuz it's black ; and if any other black number came up I would win $10 less the $5 bet on the "5-number bet".

So 58% of the time I would make a profit, but 42% of the time i would lose $15 ...

I hoped someone would tell me if my math is correct or if not, what would be correct..
