Misleading solution for chap06 exercise "honest members"

[johanwiden]

I believe it is a lucky coincidence that table[312] or so gives a good likelihood. I believe that one should search table[] for the index that gives the posterior that has a max_prob() closest to 312. I think this becomes clear if one plots the distributions for a few indices, say [0, 180, 360, 530]. Also if one considers that he values 50% and 90% are somewhat arbitrary.
