Probability and Combinations

What if you had a bag that contained 5 red marbles, 4 blue marbles, and one white marble? You randomly pick three marbles from the bag. What is the probability that one of those marbles is the white one? After completing this Concept, you'll be able to calculate the probability of events like this one involving combinations.
