Probability In A Five-Team Tournament
In a five-team tournament, each team plays one game with every other team. Each team has a 50% chance of winning any game it plays. (There are no ties.) Compute the probability that the tournament will produce neither a undefeated team nor a winless team.
God has made the integers, all the rest is the work of man.

Re: Probability In A Five-Team Tournament
You made a little mistake. In the third case, (which produce one undefeated team and one winless team) i think you have to permute the two teams. That means there are 5P2 such choices not 5C2.
