Re: Extinction (of marbles)



Stan Friesen writes, "You shouldn't be asking about red specifically, you
should be asking what the probability that *some* color (any color) is
missing from the final pick of survivors.".  I would posit that you would
need to consider the number of species of all organisms extant at the time,
and the number of those that were dinosaurs, and ask the probability that
*all* of the dinosaur species would be missing, and *most* of the mammals
would survive, and so on.  If randomness of extinction is the underlying
question, then the smallest group to be considered must be based upon
reproductive capability, ie, species, not mammals v dinos v amphibians.
