I've started making a back testing simulation for the Hi LO exchange game. Unfortunatly it's my maths that is a bit rusty and letting me down. Can anyone help me with the formula for calculating the odds of the next cards. I can calculate tI like 'unfinite'https://community.betfair.com/general_betting/go/thread/view/94082/28964881/help-needed---calculating-probability?post_id=517214861#517214861I like 'unfinite'Tue, 06 Mar 2012 03:49:54 -0600If there are an infinite number of decks available then the odds for each rank will be as to a full deck.So if Ace high only,say,and an Ace is first card turned the probability of lower will be 48/52 not 48/51.https://community.betfair.com/general_betting/go/thread/view/94082/28964881/help-needed---calculating-probability?post_id=517139655#517139655If there are an infinite number of decks available then the odds for each rank will be as to a full deck.So if Ace high only,say,and an Ace is first card turned the probability of lower will be 48/52 not 48/51.Sun, 04 Mar 2012 06:42:30 -0600infinite that ishttps://community.betfair.com/general_betting/go/thread/view/94082/28964881/help-needed---calculating-probability?post_id=517138299#517138299infinite that isSun, 04 Mar 2012 05:43:38 -0600How do you do this when xgames use an unfinite deck?https://community.betfair.com/general_betting/go/thread/view/94082/28964881/help-needed---calculating-probability?post_id=517138289#517138289How do you do this when xgames use an unfinite deck?Sun, 04 Mar 2012 05:43:07 -0600Thanks Lori. I was hoping it would be fairly simple but it seems like a bit of a nightmare ! I can simulate the entire game using python it's just the odds Im struggling with. Back to school for me I guess !https://community.betfair.com/general_betting/go/thread/view/94082/28964881/help-needed---calculating-probability?post_id=517138283#517138283Thanks Lori.
