Dmark, do you know about combinatorics? This is how many variations of a hand a player can have.
For example, our villain can have 6 combos of AA:
1) A
A
2) A
A
3) A
A
4) A
A
5) A
A
6) A
A
Ditto for 99-KK.
But 88 is rarer. The 8
on the board reduces the possible combinations of 88. Do you know how many combinations of 88 (that is, sets) he can have?
I think it's safe to assume he's not raising 44 utg+1. And people will overplay overpairs all the time, so we should probably put 99-AA in his range. But if we want to discount it (give him a little credit for being careful post flop with an overpair), we can leave out 99 and just give him TT-AA.
So dmark, how many combinations of hands do we beat (and how many beat us) if he has {88-AA}? How many if he has {88, TT-AA}?
Then you should be able to answer your question, although there are a couple details I've left out that we can proceed to next.
