Re: How your hole cards affect the flush chances in Omaha.
I'm not sure I understand the question.
Are you asking about the chance of flopping a flush given that you hold 4 of a suit? Hitting a flush by the river?
Obviously, if you hold 4 of one suit, you have the best chance of flopping a flush or hitting one by the river, and you don't need the hypergeomtric function to calculate it. Eg, given that you hold 4 clubs, the chance of flopping a flush is:
1 - ((39 choose 3)/(48 choose 3)) = .471
If you hold only 3 clubs, that chance drops down to:
((10 choose 2)*39 + (10 choose 3))/(48 choose 3) = .108
Again, please clarify if this is not what you were asking.
