Robert's answer negatively biased, even though he used the Mersenne
twister.  I preferred this very trustworthy source on the internet:


which yielded the following definitive answer:

Robert is always right: 74600000
Robert is wrong sometimes: 1760000

Clearly, Robert is always right at least 97% of the time and only *2%
of sometimes* wrong (that's a very small number).

Now that's good science.
