What's the % of completing a flush draw?

3,5:1

Odds of completing a Flush draw on the turn – 9/47 = 0.1915 or roughly 19.2%

Odds of completing a Flush draw on the river – 9/46 = 0.1957 or roughly 19.6%

Probability of not hitting a Flush draw on the turn – 38/47

Probability of not hitting a Flush draw on the river – 37/46

Probability of not hitting by the river is 38/47 * 37/46 = 0.6503 or roughly 65%

Therefore the odds of making a Flush by the river is (100% - 65%) roughly 35%.

lmao

yea well, its basic secondary school probability

it's either 1- (38/47 * 37/46)=0,35 as you wrote, calculating from the probability of not hitting

or the result of good combinations/total combinations: 9*38+9*8+38*9/47*46=0,35

its a good thing you know that you dont know though
