Knowing the probability of making a specific hand in poker can be done by calculating poker hand odds. Knowing how many outs you have will give you the possibility of calculating the number of times you will hit your hand by the river.

Lets say your'e dealt A-9 of hearts in Texas Hold'em and the flop comes up showing two hearts. Your poker hand odds for hitting another heart by the river will be approximately 36%.

You can figure this out by first finding the number of outs that you have. Outs are the number of cards remainig in the deck ( not visibe to you) that can help you make your hand.

poker hand odds So if we are using the hand above as an example and you hold A-9 of hearts and catch two hearts on the flop, than you have 9 more hearts in the deck that can help you complete your flush. 2 hearts in your hand + 2 hearts on the table - 13 hearts in the deck = 9 outs. If you multiply your number of outs by 4, than you will get an approximate percentage of hitting your hand by the river (9x4=36%).

You must multiply your outs by 2 to find out your chances of catching a heart only at the turn or only at the river. (9x2=18). So your chances of hitting your flush on the flop is 18%. If you miss the flop than your chances of catching your flush on the river is also 18%. This gives you a 36% total chance of hitting your hand by the river.

The calculation above is all you realy need, but here is a 100% correct way of calculating "poker hand odds":
After the flop, your percentage of hitting your card is: 1 - [ ((47 - Outs) / 47) * ((46 - Outs) / 46) ] (47 equals the remaining cards left in the deck.)
