Follyfoot Posted May 14 VT Supporter Share Posted May 14 Me and the Mrs have the same PIN numbers for our main bank accounts that we have both had since before we met would be interesting to know what statistically the chances/odds are on that Link to comment Share on other sites More sharing options...

Although ironically not for my own credit card. Link to comment Share on other sites More sharing options...

I disagree. Whatever one number is, the other has to match, the first number isn't relevant Link to comment Share on other sites More sharing options...

Whatever one number is, the other has to match, the first number isn't relevant This just isn't right Let's invent some numbers, the chance of any random person having 1234 is 1 in 100, because it's an incredibly common and stupid pin. The chance of any individual having a pin of 9307 might be 1 in 20,000 because it's not a sequence, a date, repeated numbers, etc If Follyfoot's pin is 1234, the chances of him meeting a partner who happens to share his pin is substaintially more likely than if his pin is 9307. So, in the interest of calculating the odds of it, we need @Follyfoot to tell us his pin. 4 Link to comment Share on other sites More sharing options...
blandy Posted May 14 Moderator Share Posted May 14 22 minutes ago, bickster said: I disagree. Whatever one number is, the other has to match, the first number isn't relevant You're both right. If the second PIN is randomly chosen, then it's 1 in 10,000, but... They're not. banks don't issue some numbers as the initial PIN, and people don't randomly select their own PINs - cards don't get sent in the post with 1111, or 1234 etc, because, obvious. Folk often pick birthdays, or years of birth, or etc. Which makes it way more complicated. Link to comment Share on other sites More sharing options...

It is a random pin number beginning with an 8 The Mrs thinks it was a sign we should be together, I think it is a curse 3 Link to comment Share on other sites More sharing options...

Yes but forget the exceptions, they aren't that significant. 1:10,000 is a ballpark figure What @Davkausis trying to say is the distribution of PINs isn't equal as the above graph shows but that is because people have the ability to change their PIN and that again isn't relevant as both these PINs were issued by the bank 1 Link to comment Share on other sites More sharing options...

bickster Posted May 14 Author Moderator Share Posted May 14 That does make me wonder how many people have never changed their bank issued PIN though 1 Link to comment Share on other sites More sharing options...
