Question

A bag contains 2 red marbles, 9 blue marbles, 18 green marbles, 10 purple marbles and 7 yellow marbles. If you pull out one marble first, replace it inside the bag and pull out a second one, what is the probability of pulling out a blue marble in the second case?

If we didn't replace the marble.what is the probability of pulling out a blue marble in both cases?
(brainliest and will be followed if the answer is detailed)

Answer 1

The probability of getting blue marble in the second case is 1 by 8 because  first time you may pick the blue marble and in the second time also the same. And even blue marble may be replaced right. Hope that this answer may help you. Thank you
