Question

Hannah has a bag containing 2 Red, 4 purple, 4 Blue and 2 Green

marbles that all are the same size and shape. What is the
probability of randomly choosing a Red marble replacing it, and
then randomly choosing a Blue marble?

Answer 1

1/18

Explanation:

there are 12 marbles in the bag

P(choose red) = 2/12 = 1/6

P(choose blue after replacement) = 4/12 = 1/3

P(choose red, then blue with replacement) = (1/6)(1/3) = 1/18
