Medium Data Analysis And Probability Basic Probability

A bag contains 5 red marbles, 3 blue marbles, and 2 green marbles. If you randomly select one marble from the bag, what is the probability that the marble selected is blue?

To find the probability of selecting a blue marble, you can use the formula:

$$ P(Event) = \f\frac{Number \ of \ favorable \ outcomes}{Total \ number \ of \ outcomes} $$

$$ \frac{1}{4} $$

$$ \frac{3}{10} $$

$$ \frac{1}{3} $$

$$ \frac{2}{5} $$
