Hi again.
What are the odds of correctly guessing someone's Social Security number?
It has 9 digits.
I'm asking because someone claimed to have seen this in a dream.
Oh, and Elendur, I would love to see another screenshot of your work.
The easy answer is One in a Billion. That is not quite correct since there are less than a billion possible numbers. This article explains how only 745,395,443 numbers are available.
