Hello guys. I have a math problem I hope someone can help me with. I sometimes play roulette if I'm down to get back in the game. I play 3 units on the 2nd and 3rd quadrants and 1 unit on 2 corners of the first quadrant. From my calculations thats 86% of the board covered. Correct me if I'm wrong. Playing only one 0 on the board. If I was to lose the fisrt round, what would I need to double and saying I lose the second round what would I need to bet on the third round to not break even but win the third round. Thanks I know I would be risking a ton I just figure the odds would be very much in my favor after 2 losses.
