| Aug 3, 2017 at 20:31 | comment | added | Henry | @6005: It can in fact first happen as a random variable at any time from $3$ through to $2\times 365+1=731$, with median, mode and mean as stated, and standard deviation of about $32.832597$ | |
| Aug 3, 2017 at 19:05 | comment | added | Caleb Stanford | What do you mean by the median, mean, and mode? There is just one first time this happens, at $88$. I am having trouble understanding | |
| Aug 2, 2017 at 23:04 | comment | added | Henry | Deeper calculation gives rounded probabilities of at least three people sharing a birthday of $84-0.464549768$ $85-0.476188293$, $86-0.487826289$, $87-0.499454851$, $88-0.511065111$, $89-0.522648262$ so the median of the first time this happens is $88$ though $87$ is close, while the mode is $85$ and the mean is about $88.73891765$ | |
