Question

Teri has a bag of colored marbles. Five marbles are red, four are green,

ten are blue, and one is white. Marbles are randomly selected out of the bag. What is the probability of selecting a green marble and then a blue marble with replacement?

Answer 1

Explanation:

Total marbles = 20

No of white marbles = 1

No of red marbles = 5

No of green marbles = 4

No of blue marbles = 10

.Probability of green marble = 4 / 20 = 1/5

Probability of blue marble = 10 / 20 = 1/2
