A bag has three marbles: one red, one blue, and one yellow. The marbles are pulled from the bag one at a time without replacing them. In how many different orders could the marbles be pulled from the bag?
1 answer
Since we pull the marbles out without replacing them, there are 3 choices for the first marble, 2 choices for the second marble, and 1 choice for the third marble. This means there are $3\cdot 2 \cdot 1=\boxed{6}$ different orders in which the marbles could be pulled from the bag.
