4 matches are to be played in a chess tournament. In how many ways can...
Solution:
There are two possible outcomes for each match, either player 1 wins or player 2 wins. Thus, for each of the four matches, there are 2 options, giving a total of 2*2*2*2 = 16 possible outcomes.
However, we also need to consider the possibility of draws. If a match can end in a draw, then there are 3 possible outcomes for that match. Thus, the total number of possible outcomes is 3*3*3*3 = 81.
Therefore, the correct answer is option C, 81.
