As a child I had a bike with the alphanumeric serial AD93847. A few weeks ago I registered with a web service and was issued the registration Alphanumeric AD93847 - Identical to the bike reg. What is the probability for this happening?

You have alreday asked this in science and got an answer.

How can you remember the serial number of a bike you owned when you were a child?

Dunno - prob because i loved it - it was a raleigh chopper and my mum told me to memorise the frame number in case it got stolen and today my memory is really very poor indeed but I'v never forgotten that frame number :-)

I get it at 67.6 million to one. About as likely asd my b/f actually listening to something I say.

I first met my wife on a beach on holiday. What were the chances of that- there are billions of people in the world but she just happened to sit next to me. A billion to one chance? Of course not.
Or yesterday I thought of my mum and she rang a second later. Thousand to one chance of her ringing at that moment? Of course not. What about all the times she's rung when i wasn;t thinking of her.
What about all the numbers and codes you've had that never cropped up.
Million to one chances occur several times a day somewhere.
