Assuming nobody looked at their cards first, the probability of a 6,7, or 8 is 1 minus the probability of no 6,7,8 = 1 - (40/52)(39/51)(38/50) = 55.3%. He had a 9.4% edge. It would be 14% if he looked at his cards and didn't have one assuming others would always bet if even if they didn't have one.

I've been getting people to give me 2-1 that a pair will appear in 5 cards. It's really about even money, so half the time I win the big bet, and half the time I lose the small bet, so I average winning the small bet. That's a 100% return on my money. One guy asked me if I had no shame, which of course I don't. "It's immoral to let a sucker keep his money." People who can't figure probabilities and bet anyway deserve to lose money to those who can. [img]/forums/images/icons/grin.gif[/img]
