Thanks to the Dice Man for his in-depth calculations and explanation, but there is a simpler, common sense way of saying what he says. I'm sure you'd all agree that every individual bet on a roulette table gives the house an edge, yes? In other words, any individual bet is -EV. That being accepted, how can any combination of bets be +EV? Multiple negative values never add up to a positive value. I suspect the best you can hope to do is reduce your variance as much as possible and get lucky now and then!
