Question

ndrew has a bag that contains 8 blue marbles, 6 red marbles, and 10 green marbles. He selects a marble, replaces it in the bag, and then selects another. What is the probability that the first marble is blue and the second marble is red? A. B. C. D.

Answer 1

Answer:

Blue: 33.33%

Red: 25%

Step-by-step explanation:

Andrew has a total of 24 marbles in the bag.

his chance of picking a blue marble the first pick would be 8/24

he then replaces the marble... he does not set it aside in the second pick, so the fraction would still be over 24 for the next pick.

out of the 24 marbles, there is only 6 red ones. so his chance of picking a red one would be 6/24.

the percentages for these are

Blue: 33.33%

Red: 25%
