- Your numbers above do not make sense. As I recall, on a 12, both
- Pass and Don't Pass loses, right? In that case, the probability
- of a 12 = 1/36 = 2.7778% is both lose. With your numbers, it's
- 1.4%. Something wrong there. My numbers are:
-
- Pass 49.292929%
- Don't Pass 47.929292% (49.3182% if 12 is a push for Don't Pass)
- Both Lose 2.777778% = 1/36
-
- You don't even need fancy calculations ..
-
- Conditional Prob. based on 1st Roll
- First Roll Prob of 1st Roll Pass Don't Pass
- 2 1/36 0 1
- 3 2/36 0 1
- 4 3/36 1/3 2/3
- 5 4/36 2/5 3/5
- 6 5/36 5/11 6/11
- 7 6/36 1 0
- 8 5/36 5/11 6/11
- 9 4/36 2/5 3/5
- 10 3/36 1/3 2/3
- 11 2/36 1 0
- 12 1/36 0 0 (or 0.5)
-
- For each line, all you need to do is multiply Pass/DP numbers
- by the "Prob of 1st roll" number and sum down each column.
-
- I always play Don't Come. If you think about it, people usually
- leave the table after a 7-out. If you play Don't Come, that means
- you leave on an up spike (especially if you had bets on 3 or 4 numbers
- plus the don't pass bet). And if you took odds on your don't come,
- it can be even a bigger spike.
