no commision on banker. any advantage we can get or any way to estimate edge.
Probability of rolling 8 with two fair 6-sided dice = 5/36
Probability of rolling 9 with two fair 6-sided dice = 4/36
Probability of rolling anything else with two fair 6-sided dice = 27/36
Win/Loss to Player in case of an 8 roll = 2
Win/Loss to Player in case of a 9 roll = 3
Win/Loss to Player in case of any other roll = -1
Expected Win/Loss to Player = (5/36)(2)+(4/36)(3)+(-1)(27/36) = -5/36

Hence, the player can expect to lose approximately 14 cents per dollar wagered every time he plays this game. There is no way to get an advantage; stay away from this side bet.
