My brother wants me to come to the casino with him, right now. He's got this idea with Roulette where I put $5 on red and he puts $10 on black, and no matter the outcome (unless it lands on the green - rare) worse case scenario we break even, best case we are up $15. Obviously, if this works, we will be using much larger numbers. I can't find a flaw in this aside from the slight risk of hitting green. Someone tell me why I should go do this right now. EDIT: Thinking about it more (with a little outside help) this won't work at all.
