The source of the discrepancy lies is whether or not to count ties. I prefer to count ties as money bet and others do not. I&#8217;m not saying that one side is right or wrong, just that I prefer counting them. If you don&#8217;t count ties as money bet then you should divide by figure above by the probability that the bet will be resolved in a win or loss (35\/36). So 1.364%\/(35\/36) \u2248 -1.403%. This is the house edge assuming that the player never rolls a 12 on the come out roll.<\/p><\/blockquote>\n<\/div>\n<\/div>\n<div class=\"migrated-reply\" style=\"border: 1px solid #eee;padding: 15px;margin-bottom: 15px;border-radius: 5px\">\n<p><strong>Posted by:<\/strong> Guest on August 23, 2012, 5:54 pm<\/p>\n<div>Right click on the chart and chose View Image to see the full chart:<\/p>\n<p>\t<img decoding=\"async\" src=\"http:\/\/i45.tinypic.com\/jpx3ps.jpg\" alt=\"\" \/><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>&#040;&#040;-8\/36&#041;+&#040;3\/36&#041;&#041;-&#040;1\/36*3\/9&#041;*3-&#040;1\/36*4\/10&#041;*4-&#040;1\/36*5\/11&#041;*5-&#040;1\/36*5\/11&#041;*5-&#040;1\/36*4\/10&#041;*4-&#040;1\/36*3\/9&#041;*3+&#040;1\/36*6\/9&#041;*3+&#040;1\/36*6\/10&#041;*4+&#040;1\/36*6\/11&#041;*5+&#040;1\/36*6\/11&#041;*5+&#040;1\/36*6\/10&#041;*4+&#040;1\/36*6\/9&#041;*3=-0.0136363636363638[\/tds] [\/tables][clear][\/clear] Replies: Posted by: Guest on August 20, 2012, 9:23 am There are two acceptable results for the Don&#8217;t Pass bet: -0.01364 = -1.36% or -0.01403 = -1.40% The formulas are different.
