Depends on probability measure we will choose. The true is that probability that in two coin drops we will get two reverses is 1/4, but true is, too, as Newton said, it's 1/3, because if in 1st drop we don't get reverse we don't need to drop again. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
