You could do it like so:

On an uncoordinated hand he is lets say 30% likely to have to a weaker pair, 20% likely to have topset, 20% likely to have bottomset, 20% likely to have an overpair.

That would mean you win 30% of the time.

BTW in my opinion you don't need reads at this level. Just play straightforward and solid. Call down big pots, fold small pots (most of the time) if you aren't sure.
