| Oct 4, 2021 at 13:20 | comment | added | Henry | It you have a small example where it is wrong then I would interested. It seems to be correct for 2 "days" and 3 "people" | |
| Oct 4, 2021 at 13:17 | comment | added | R.. GitHub STOP HELPING ICE | @Henry: Oh, I see the number of days embedded in that answer as an aside. Thanks. I'm not entirely sure it's right though. I tried working it out last night and came up with something similar but it was clearly wrong for trivially low values of $n$ and $m$. | |
| Oct 4, 2021 at 13:17 | comment | added | Henry | Look at the third point in my answer | |
| Oct 4, 2021 at 13:15 | comment | added | R.. GitHub STOP HELPING ICE | @Henry: AFAICT those are both about counting people not counting days. | |
| Oct 4, 2021 at 13:10 | comment | added | Henry | math.stackexchange.com/a/1366028/6460 may help. In terms of your variables it is $n - n \left(1-\frac1n\right)^m - m \left(1-\frac1n\right)^{m-1}$ | |
