The outcome of a game is win, lose, or draw (W, L, D). 11 games, 22 teams means that no team plays more than one game. Since three are 3 outcomes for each game the total number of outcomes is 311=177,147 ranging from all games won to all drawn.
If a draw is counted as a non-win, then the number of outcomes of 11 games played simultaneously is 211=2,048 ranging from all 11 games won to all no-wins. The chances of guessing the win/no-win result of all 11 games is 1/2048.
