The wonderful Wizard of Odds has a nice explanation on the blackjack "in-between" side bet but I'm not quite sure how to read it. The explanation is here: http://wizardofodds.com/blackjack/appendix8.html#inbetween What I don't understand is how to read probability column of the chart. For example, it says if player's first two cards and dealer's up card form a three of a kind, then player wins 30 to 1, which I get. But what I want to know is what are the odds (x:y) of the event happening (or not)), is it 40 to 1 against? 50 to 1 against? 100 to 1 against? I suspect that information is in the probability column but do not know how to read it. Thanks!
