HARDEST QUESTION I CAN THINK OF

[bob2007]

I donno the answer to this problem, but I'm hoping some of you could solve it for me.

What is the probability of

1) top pair
2) bottom 2 pair
3) middle 2 pair
4) top 2 pair
3) three of a kind
4) nut straight

from the flop, being the winning hand.

thanks,
