Probability of Drawing a Blue Marble

In a bag of marbles, there are 3 red marbles, 2 blue marbles, and 5 green marbles. If a marble is drawn at random from the bag, what is the probability that the marble drawn is blue?

To find the probability of drawing a blue marble, we first need to determine the total number of marbles in the bag.

Use the formula for probability: $$ P(A) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} $$
