The distribution of Prime number may offer you a estimate of the probability.
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!
Do you have a large source of social numbers to study ? About one hundred thousand would already be a good estimate ...
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
