Probability in Real Life

Deion has two bags of marbles. In the bag labeled ‘A’, he has 3 green, 4 blue and 10 yellow marbles. In the bag labeled ‘B’, he has 13 green, 5 blue, and 12 yellow marbles. Deion wants the bag with the highest probability of selecting a blue marble. Which of the following statements is true?

• It does not matter which bag he chooses because the probabilities are the same.
• He should choose Bag B because there are fewer blue marbles.
• He should choose Bag A because the probability of selecting a blue marble is higher.
• He should choose Bag B because the probability of selecting a blue marble is higher.
