This is a discussion on Flush within the online poker forums, in the General Poker section; if you have 4 suited cards after the flop you have a 38 percent chance of hitting it on the turn or river. my tip

If you have a 4flush you need one of 9 cards out of 47 possible cards left left to complete.
(9/47)*2 (for turn and river) = 0.383 =~38% If you include the possibility of 2 consecutive flush cards though, it's (9/47)*2 + ((9/47)*(8/46)) = 0.416 =~42% I think, anyway.

Jeterkid your math is way off.
When calcualting pot odds to hit a draw such as an openended straight draw (8 cards that help you) or a flush draw (9 cards that help you) you take that number over the total number of unseen cards, not the # of cards left in the deck to be dealt. So to hit an openended straight draw on the NEXT card you take 8/47 which is 17%. To hit a flush on the next card it is 9/47 or 19%. If you are calculating odds on hitting a flush on the next two cards (after the flop) you take the odds of hitting on both cards individually: 9/47 and 9/46 and add them together. 9/47 = .1914893 9/46 = .1956521 added together they equal ~ .387 or 38.7% Dorkus...to calucate running flush cards for example you take: 9/47 multiply in 8/46 (.191489 x .1739130) = .033 or ~ 3.3%, so for those of you who chase running flushes, you will only hit them around 34 times out of 100.
