• Consider three football teams A, B and C. In a regular game, A beats B with probability p and beats C with probability q. C is a better team than B, so p> q. To win the tournament, A needs to win two games in a row out of three games against B and C, and it can't play two games in a row against the same team. A can either select to play these three games as B-C-B or C-B-C. Show that A maximizes the probability of winning the tournament by playing against the better team C, twice. |
