Actually my question is one part of two questions. Supposing I have open ended straight on the flop, my outs are eight, which has the probability of making the straight is 32%, which can be hand calculated (as mentioned in one of your previous responses) or from published statistics as this one. Now with this number how to find the probability of winning against one opponent holding any card. Against two, against three and so on.
I tried the apps you have mentioned. They are so confusing. I gave up. May be they are giving such stat. If they do what kind of calculation they make.
I posted the second part of my question because it looked simple enough of a probability question. May be its not.
