    Re: Probability

    Think in terms of 'league table' listing the number of wins, draws, and losses for each team. Be aware that each one of 5 teams has played 4 games since each team has four opposing teams.

    One such possible 'league table' could look like:

    W D L
    4 0 0 --> 4 wins
    1 2 1
    1 2 1
    1 2 1
    0 0 4 --> 4 losses

    Take it from there.

    All possible outcomes for one team are given in following table :

    \begin{array}{|c|c|c|} W & D & L \\\hline4&0&0\\3&1&0\\3&0&1\\2&1&1\\2&0&2\\2&2&0\\  1&0&3\\1&3&0\\1&1&2\\1&2&1\\0&1&3\\0&3&1\\0&2&2\\0  &4&0\\0&0&4\\\end{array}

    Hence , probability for both cases is :

    P=\frac{1}{15}
