Response:
Use             Number of ways $200 more can happen
                   Total number of possibilities

           = 50
              500

          = .10

“There's no sense in being precise when you don't even know what you're talking about.”

 John von Neumann quote
 
There is no philosophy which is not founded upon knowledge of the phenomena, but to get any profit from this knowledge it is absolutely necessary to be a mathematician.
