Odds Question

I must apologize first because I'm sure someone has posted this previously, but I can't find it.

Let me give the hand history so my question will make more sense first.

I limp with 55. Board comes 5-x-x with 3 hearts. I bet, guy raises. I'm almost sure he has the flush. What are the odds that the board pairs so give me the boat?

ok, I hope I'm right..

There's 47 cards unseen and 7 of them will pair the board or give you quads.. so.. (40/47) * (36/46) = 66.6% chance of you not making a hand better than a flush.

This is assuming the turn doesn't hit it, adding 3 more outs on the river there's a 33% chance of making the better hand.

I'm probably wrong but I tried.

Code:

Holdem Hi: 990 enumerated boards containing Th 5h 3h

You're good at math, BeeJall.
