Probability of Drawing a Blue Marble

In a bag, there are 4 red marbles, 3 blue marbles, and 2 green marbles. If one marble is drawn randomly from the bag, what is the probability that the marble is blue?

To determine the probability of an event, you can use the formula:

$$ P(A) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} $$
