There is a a boo-boo on the Spring, 1999 final. With the values given for the
E's in problem #7, p = 0.5 is not an equilibrium -- it should be p =
0.167. If one uses p[0] = 0.1 and p[0] = 0.2, one gets the same
phenomenon as we indicate, though with all new values, but the easier fix is to swap the values of E[SS] and E[TT].
