4/50 *3/49 *9=0.044081633
There are 50 unkown cards, so some has to first be dealt one of the four kings; next they have to get one of the three remaining kings out of 49 unknown cards. Finally there are nine people so multiply by nine.

To put it another way if you are dealt KK 1000 times at a 10-hand table its likely 956 of those times you won't be up against someone with pocket Aces.

If you're looking for the probability that a specific opponent has K-K, then it's simply C(4,2)/C(50,2) = 0.48979591%.
If you're looking for the probability that at LEAST ONE opponent has K-K, then it's:
9 * 6/C(50,2) - C(9,2)/C(50,4) = ~4.39%
You need the inclusion/exclusion principle to get this one exactly right.
