Still working on the odds of us being against another Flush.

5 flush cards out of 13 down accounted for, 8 cards left.
(8/47)*18=3.06 flush cards

I can't get a lock on this but I did find a thread the confirmed there are 3.06 flush cards in my opponents hands.

Can anyone tell me what the odds are of 2 out of 3.06 flush cards being dealt to the same hand (one of the 9 other hands)?

Edit: My best guess is:
There are 3.06 flush cards to be dealt out of 18. After that there are 2.06 cards to be dealt out of 17.

So, 3.06 favorable events out of 18 + 2.06 favorable events out of 17.

OR

3.06/18 + 2.06/17 = .29 or .3% chance of happening.
