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%
