comment maybe this sum have approximation $\sum_{k=0}^{n}\binom{n}{k}^3\approx\frac{2}{\pi\sqrt{3}n}\cdot 8^n,n\to\infty$
See en.wikipedia.org/wiki/Laplace's_method.

comment A lemma on the growth of the number of certain edge paths for a given train track
This lemma is at the bottom of page 22: www-bcf.usc.edu/~fbonahon/Research/Preprints/Bouquin.pdf The proof is on page 23. What's the problem? The basic idea is that because the arcs are embedded, you only get a polynomial number of choices on each piece (each switch of the train track).

comment Simple probability question, balls and bins
@Zev Chonoles: I'm not upset with you, but it's odd that you responded within minutes to my response to whuber, while his nasty comment was left for weeks.

comment Simple probability question, balls and bins
@Zev Chonoles: I think you missed whuber's snarky comment. I'm glad he had the decency to delete it after I responded; too bad it was up for weeks before I noticed, and that he doesn't have the decency to apologize. I reserve the right to defend myself from additional attacks. Would that you were so eager to delete his comment when he made it.

comment Simple probability question, balls and bins
Here you might have missed the context of the comments on the deleted answer, where multiple people were repeating that I was wrong when I pointed out simple cases which my answer handles correctly, but which were not enumerated correctly by the then-accepted answer. The pattern is that I don't like it when I post something correct, and then multiple people say something clearly incorrect is better. I'm not always right, but I value correctness, and having a club of people praising each other's incorrect answers and voting down my correct answers is intolerable to me.

comment Simple probability question, balls and bins
@whuber: I spent hours showing that the accepted answer was incorrect. You made a stupid comment on my correct answer, objecting to my use of a prior on a problem tagged Bayesian, where everyone else uses priors, and where optimization with no prior does not make sense. You had no objection to the incorrect, accepted answer which used the same prior. You refused to apologize or communicate with me other than questionable uses of your moderator powers. This is unacceptable to me, so I will no longer contribute to CV. I do not understand your rudeness or disrespectful attitude.

This is not probability, this is combinatorics. Also, please use the homework tag for any exercise like this.

comment Simple probability question, balls and bins
There is a flagrantly incorrect answer that was voted up and accepted, while people voted down my correct and informative answer. I'm done with this question and maybe this site. This is a waste of my time.

For more information on the inclusion-exclusion method, please follow the link to Wikipedia. That explains why I have a sum indexed like that. You can check it against the explicit example I did for $4$ bins and $6$ balls. If that's not enough exposition for you, ask someone else.

comment Simple probability question, balls and bins
I said "Let's count the configurations, then divide by $m^n$." Then I counted the configurations as $m$ times that sum. How can you say that's just a hint? I'm sorry you don't think that sum is as clear as an incorrect answer, but not everything is that simple.
