You're welcome.

Let's say you're holding KK, and for some reason you're sure that an opponent is either holding AA, AK, or QQ. Also on the board, there's a Q showing.

You now have some information on the chances that the person is holding the different hands that you put them on:

AA = 4*3/2 = 6
AK = 4*2 = 8
QQ = 3*2/2 = 3

So in this particular situation, it's still slightly more likely that the person is holding AK than AA (8/17 vs 6/17).
