Newbie question re books on poker statistics

[Scorpius]

If anyone knows of any good poker statistics books that deal with probabilities and odds, etc. and how to calculate them, how to use them in poker, etc., I would appreciate your posting them. My Omaha/8 game has improved dramatically just by not playint too many hands and by paying more attention to how the other players are playing, but I am still missing out on the math involved. I know it is an essential part of the game...calculating pot odds, probabilities of certain hands coming up at certain times, etc., so any help would be appreciated. Thanks.
