[extropy-chat] calling all bayesians

[spike]

Guys help me eff this real-life effing problem:

I build 150 droobs and use 131 of them in my freem.  I
test the remaining 19 spares destructively and find that
all are good.  From that information only, what is the
probability that all 131 droobs are good?

I have four Monte Carlo sims chewing on this problem
but they are giving me puzzling results.  A closed-form
solution to this would be impressive, winning my
undying respect.
