It's even worse if you represent the primary numbers in binary notation. Every prime number greater than 10 ends with the digit 1 ;) [edit typos]

- fredley 11y agoWhich leads to the interesting question: if this happens in base 10, but not (trivially) in base 2, what other bases does it happen or not happen in?
- ghurtado 11y agoI think you may have missed the joke.
- allemagne 11y agoHe got the joke, but was also taking it seriously as a phenomenon that could have interesting implications. This finding obviously doesn't hold base 2 (more accurately, isn't an applicable concept), and apparently becomes more pronounced in base 3.
- Phemist 11y agoOnly in bases that are itself prime ;)
- kba 11y agoIt's a joke. The last digit of a binary number is parity (odd or even). Since all primes (except for the number 2 [or 10 in binary]) are odd, the last digit will of always be 1.
- fredley 11y agoYes, I am aware of that (hence 'trivially') thank you!
- pc86 11y agoIn the other HN post there is a comment stating that it's a fairly significant occurrence in base 3 as well.
- Houshalter 11y agoWhat about the second bit though? There might be a correlation in other digits too.
