Hey there!

I have a question about outs and odds

For example, Imagine that I have an open ended straight draw after the flop is revealed: there are 8 cards that help me.

So, the deck has 52 cards. Two are in my hand, three are on the flop, so there are 47 cards remaining

The probability that one of those 8 cards comes is: 8 divided by 47 = 0,1702

But in the Outs and Odds chart of the bronze articles, the odds from flop to turn of an OESD is 5:1, i.e., 1/5 = 0,20

Same thing for Flush Draw: 9 outs in 47 cards -> 9/47 = 0,1914

In the chart, it comes 4:1, 1/4 = 0,25

what the hell??
