The odds of winning a contest 2007-07-29
Kevin pose la question :
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?

BEDMAS? 2006-11-29
john pose la question :
I won a contest and they have a confusing format for the STQ. here it is:
11 (+) 44 (x) 2 (-) 10 (%) 25
I've never seen brackets around the operands and wondering how to treat it. 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?
