So, did anyone else think Marilyn blew it yesterday?article
John
P.S. For the "Parade Magazine-deprived," Marilyn had the cover
this week and the lead question, printed on the cover was, "Your doghas a
litter of four. Is it most likely that two are males and two are
females?"
Of the sixteen possibilities, 8 are of the 3 + 1 variety, while only 6
are
of the 2 + 2 variety, so it would seem that Marilyn is correct in her
answer that it is more likely that the litter of four would have three
of
one sex and one of the other sex than that it would be a 2-2 split.
(Always assuming both sexes equally likely on each birth, of course.)
