Forum:KB:Calculating the odds

I remember in Episode 5, C-3PO was always calculating the odd ex. 725 to 1 chance of surviving in the cold of Hoth, 3,000something of navigating an asteroid feild and more recently 10,003 to 1 of a clone being in the Umbaran blockade ship. Where are these droids getting these numbers from, and is possible to calculate probabilites like this in real life?24.193.145.164 07:41, December 27, 2011 (UTC)
