If you reach the flop with a number of outs, you’ll have to calculate your chances of hitting one of those outs on turn or river.
Suppose you hold
and the flop comes
You have a flushdraw and it gives you nine outs for hitting a flush on turn and river. If you want to know the chances of a club on the turn you divide the number of outs by the 47 unseen cards and multiply it with 100%.
For our flushdraw we have a chance of 9/47 * 100% = 20% of catching a club on the turn. To calculate the probability of catching a club on turn and river together you’ll have to calculate the chance that none of your outs will apear on turn or river.
With nine outs on the flop you have a 38/47 * 37/46 * 100% = 65% chance of not catching one of your nine outs. This means you have a chance of 1 – 65% = 35% you do hit one of your outs on turn or river.
