Likelihood AA vs KK

[Voldemorte]

Hello,

we were talking at lunch about the likelihood of having AA vs KK.
As far as I remember it is sth. like 1:210 to get Aces, so it is the same likelihood to get Kings.

We were not sure about the following solution:

(1/210 x 1/210) x (number of players) = likelihood to have AA vs KK.
