# --description--
Oregon licence plates consist of three letters followed by a three digit number (each digit can be from \[0..9]).
Oregon licence plates consist of three letters followed by a three digit number (each digit can be from [0...9]).
While driving to work Seth plays the following game:
Whenever the numbers of two licence plates seen on his trip add to 1000 that's a win.
E.g. MIC-012 and HAN-988 is a win and RYU-500 and SET-500 too. (as long as he sees them in the same trip).
E.g. `MIC-012` and `HAN-988` is a win and `RYU-500` and `SET-500` too. (as long as he sees them in the same trip).
Find the expected number of plates he needs to see for a win. Give your answer rounded to 8 decimal places behind the decimal point.
Note: We assume that each licence plate seen is equally likely to have any three digit number on it.
