12 games out of how many games? I mean, do you have to select 12 games out of the entire xbox 360 game library? In order to calculate the odds of you getting 12 correct we need to know the total number of games you have to select from. Maybe post a link to the contest itself.

Anywho, the formula for calculating the odds of you picking the right 12 games is:

n!÷(r!*(n−r)!)

Where n is the total number games you have to choose from and r is the number of games you have to get right. So if you have to pick 12 games right out of 100 games your odds are: 1,050,421,051,106,700 to 1. That's a quadrillion to one odds...a runaway star has a better chance of hitting our sun than you getting the right 12 games.
