Odds are defined as
Number_Of_Things_You_Want_To_Happen : Number_Of_Things_You_Don't_Want_To_Happen

Probability is found by taking

                      Number_Of_Things_You_Want_To_Happen
-------------------------------------------------------------------------------
Number_Of_Things_You_Want_To_Happen + Number_Of_Things_You_Don't_Want_To_Happen

So odds of 1 in 425 is a probability of 1/426.

Somebody please correct me if I'm wrong, that class was 2 or 3 years ago....
