comment Number of permutations if every element may appear in certain distance from its initial position
@GerryMyerson, sorry, for my particular problem exact answer wasn't necessary, and doc about n-case not so simple for me to read it fast.

comment Expectation of throwing $n$ balls into $n$ bins
Sorry, could you please shed some light on this formula $\binom{n}{1}\frac{1}{n}\left(1-\frac{1}{n}\right)^{n-1}.$ I see that $\frac{1}{n}$ is probability, that ball got into certain bin, $\left(1-\frac{1}{n}\right)^{n-1}$ that it doesn't in $n-1$ steps.
