[ QUOTE ]
flopped a set
6:1 to make boat/quad on turn (7 outs)
4:1 to make boat/quad on river (10 outs)
if i went all in on flop, what are the odds to make a boat/quad by showdown?

If you have no information about what anyone else has, you will fill up 7/47 + (40/47)(10/46) = 33.4%.
If you know your opponent has a flush, you will fill up 7/45 + (6/45)(9/44)+(32/45)(10/44) = 341/990 = 34.4%. The middle term comes from when the turn would pair your opponent, giving you only 9 outs on the river. It is slightly more likely that you fill up if you know your opponent is not blocking the board from pairing.

If you know your opponent has a straight or a baby flush, you get the same probability to fill up, but you also have outs to tie.
