Give a random social security number, what are the chances that it's a prime number?

I've been researching how social security numbers are given but this still seems fairly difficult to figure out. Any hints or suggestions are greatly appreciated!

The distribution of Prime number may offer you a estimate of the probability.

Do you have a large source of social numbers to study ? About

*one hundred thousand*would already be a good estimate ... (Sweating)

**Otherwise**, maybe this could help : SSN

Structure paragraph details about everything you need, I think.

For example, you could work out that :

¤ the first part is issued on geographical region -> study probability that one american picked at random is in one state

¤ the second part is issued in a weird order -> look at the order on the website

¤ the third part is issued in a linear order -> no problems here - Nov 30th 2009, 08:46 PMchisigma
Essential : how many decimal figures does have a 'social security number'?...

Kind regards

$\displaystyle \chi$ $\displaystyle \sigma$
