Re: Modeling freight car distribution.

Monon's 1,065 boxcars was 0.14% of the National Class I RR Boxcar Fleet
or about one in every 700 boxcars.

And therefore, the probability that NONE of the Monon box cars
showed up in a year's time in any particular location is less
than 6%... Or put another way, there's a 94% probability that at
least one of the Monon box cars would show up within a year, assuming
that all box cars are equally probable. (Given your theory of random
box car assignments.)
