1) How many games will be played in total, in the tournament? We can represent the results of this tournament by a directed graph: node i represents team i, and an edge exists i → j if team i beat team j. 2) Show (by example) there is a tournament that might occur, where every team is beaten by some team. The above problem suggests that it may be impossible to declare an absolute winner, as everyone may be beaten by somebody. We could relax this slightly in the following way: let's call team i a k-winner if there is a group of k-many teams that were each beaten by team i. Other teams may have beaten team i, but there is at least a group of size k that was roundly beaten by i. 3) If the results of each game are decided by fair coin flip, what is the probability that a given team i is a k-winner?
