At a local tournament, me and a friend were having silly £1 bets on flops, all cards over 8, 2 cards the same suit, really trivial stuff like that. I offered a bet at evens, that an 8, 4 or 2 would be on the flop. I know I'm getting the best of it, I was thinking probably 55/45 favourite, but he seemed to think I was 75% favourite-ish. We didn't really talk about it, but it just got me wondering what the actual odds were?
Any chance of some help please guys?
