Like I've stated numerous times, I'm more educated than you could ever wish to be. I've given the numbers, why can't you dispute them? I guess reverting to name calling is all you have left.
Since you seem so determined to prove yourself to be a total imbicile, I will dispute your numbers.
If you place a 5, 6, 8, and 9 you have 18 ways of rolling ONE of those numbers. There are 6 ways to roll a 7. So your odds of getting ONE of those numbers before you get a 7 are 3-1 in your favor.
Heres where your moron train jumps the tracks.
So for every 4 rolls, you will get one of your numbers 3 times and the 7 will come once.
The one time the seven comes you will lose 4 bets (call them units) so you are -4 units.
The three times you get ONE of your numbers you will be paid an average of 1.27-1 for a total of 3.81 units.
So, using your system, and using YOUR MATH, for every 4 rolls of the dice you will win 3.81 units and you will lose 4 units. That makes you down .19 units for every 4 rolls of the dice.
THERES YOUR MATH. Now tell me how in the hell you can argue that?
