I have N people and each of them has a uniform probability to belong to one of M countries. Now I wonder what is the distribution of the multiplicities?!(adsbygoogle = window.adsbygoogle || []).push({});

I mean the number of countries with 1 person, 2 persons, 3 persons,... (no matter which country)

Is there an equation for it?

And what if the distribution is not uniform, but I know that some countries are more popular?! (a non-uniform distribution?)

Is there a sensible measure of quantifying this redistribution of popularity?

And does power law distribution play in at some point?
