exam the students find out that the team has a 0.3 probability of
not losing the first game, and a 0.6 probability of not losing the
second game, independent of the first. If it does not lose a game,
the team is equally likely to win or tie, independent of what
happens in the other game. The team will receive 2 points for a
win, 1 for a tie, and 0 for a loss.
