random

[Laura Creighton]

Gang, you have forgot what I said about sampling error.  Lets try a different
thought experiment.

If you decide to go north or south based on whatever train arrives
first, randomly arriving at the train station will not help you because
if the trains run 1 an hour and at the 00 going n and the 10 going s
you are 5 to 1 more likely to find the next train is north no matter
how crazy your work schedule is.
