Hello anon! Thanks for your solution, it is of course correct! Always fun to see people using generating functions. How did you know to differentiate to extract the coefficient? Sorry, I'm not very familiar with generating functions still, I've been meaning to get around to it sometime soon. Is what you did explained in generatingfunctionology?

But again, thanks a lot! Amazing work and I hope you have a just as amazing day.

Nice generalization!

>Not really. Combinatorics isn't super useful for machine learning.
Well I suppose that's fine.
>this fall I'll be starting my PhD
Best of luck to you, anon. I hope whatever you face you overcome it.
>my biggest piece of advice is to get to know your professors.
Thank you for this advice. I hope I can put it to good use. In highschool I've managed to be close with teachers to the point one of our math teachers brings problems he can't solve to me and asks for geogebra/desmos help. In university that might be more challenging.
Again, good luck on your PhD journey and thanks for your advice.

I actually kind of agree with you anon. I think it would have been nicer if the problem instead asked what's the average number of records broken on a day. I don't think it's wrong the way it is asked, but it sounds a bit strange when you think about it, like you did.

On an unrelated note, I'm glad we didn't suddenly start screaming like this

I think we both deserve a reward for that.

Also not to praise myself but pog problem. I'm glad I found it and shared now.
