The odds of winning a contest 
20070729 

From Kevin: I have been asked by a customer in Missisauga to track down some odds of
winning a contest. In this contest, the last 4 digits of the winner's
driver's license number have to match the last 4 digits of a Harley VIN
number. There are 200 people maximum allowed into the drawing, 10,000 total
possible VIN combos. Would the odds be 1:50 or something other than that? Answered by Harley Weston.

I fear they want me to answer the question left to right as the answer is 4 if I use BEDMAS I get 98.6 (which clearly sounds wrong for what they want) any thoughts?
