If you belive more in math than in randomnes you should play martingale. What is the odds of red popping up yet another time...
50%
Yeah, but there's already been a lot of reds. Clearly you don't understand probability. Eventually there has to be a black, and since there's been so many reds it's very unlikely it will continue to be red.
So the chances are *way* less than 50%. Black is a sure bet.
Past observations do not affect future outcomes when it comes to randomness. If this were true casinos wouldn't have roulette. The odds red or black for double zero roulette btw are 47.37%. You will eventually lose your money and that's why Las Vegas casinos are so big. The only three ways mathematically to win (I know for sure) are positive expectation video poker, cheating (counting cards) at black jack, and being good at poker, in a casino. I personally made a lot of money at poker and video poker back when it was more profitable. I know people who make 60k+ a year playing black jack but, it seems very stressful to me.
