Final answer:
When drawing a marble randomly from a bag with different colored marbles, each marble represents a separate outcome. Hence, the number of possible outcomes equals the total count of marbles, which is 9 in this case.
Step-by-step explanation:
When a marble is drawn from a bag containing 2 silver marbles, 4 green marbles, and 3 blue marbles, the number of possible outcomes is determined by the total number of distinct marbles, regardless of color. Thus, each marble represents a unique outcome when drawn from the bag.
There are a total of 9 possible outcomes, corresponding to each individual marble (2 silver + 4 green + 3 blue).
