odds question

[damn_river]

does anyone know where to find the odds to making an openended and inside straight draw from two connecting cards for ex 45, 56, 67, 78, 89, TJ. or how i might be able to figure it out.

when i do the math myself, i get 9.8% chance of being openended on the flop.
anyone get the same or different ansers?

I did this calculation in this thread

straight draw odds

I got 10.28% for flopping an open-ended straight draw. It will be a little higher if you include flopped straights, and higher still if you include gutshots.

In any case, I'm pretty sure 9.8% is wrong, though it's close.
