Re: K-xs Close Enough to be Nut Flush?
Your approach isnt quite correct but the result is close enough. For a particular one of the other 9 at the table to have you beat he must have started with the A (1/45) and other (7/44) of the suit, times 2 because order doesnt matter. That is only a .707% probability. To find the probability for any one of the 9, subtract that from 1 (giving the probability he doesnt have it) raise it to the 9th power (giving the probability none of the 9 have it), and subtract that from 1, or 6.2%.
