Basic Probability with Colored Balls

In a bag, there are 3 red balls, 2 blue balls, and 5 green balls. If you randomly pick one ball from the bag, what is the probability that you will pick a blue ball?

To find the probability of picking a blue ball, we can use the formula:

$$ P( ext{Event}) = \f\frac{\text{Number of Favorable Outcomes}}{\text{Total Number of Outcomes}} $$
