| Aug 10, 2021 at 16:22 | comment | added | Iosif Pinelis | @kodlu : Thank you for this interesting reference. Wow, a number of well-known people studied such matters! The result most closely related to (but not quite the same as) the above one is apparently given by formula (9.5) on p. 54 of that report. | |
| Aug 10, 2021 at 15:52 | comment | added | kodlu | Diaconis and Mosteller studied 'near coincidences'. Cannot get to the paywalled paper but a long report is here (see p. 51 for a relevant approximation) statistics.stanford.edu/research/methods-studying-coincidences | |
