Question

A bag has 4 green marbles, 3 red marbles, and 3 yellow marbles. What is the probability that you pick a green marble, do not replace it, and pick a red marble?

Answer 1

Total marbles = 4 + 3 + 3 = 10

Chance of picking a red marble on 1st pick : 3/10
Chance of picking a red marble on 2nd pick: 2/9

Therefore probability = 3/10 * 2/9 = 6/90 = 2/30
simplfy 2/30 to get the final answer : )

Answer 2

Thank you so much I got 1/15 :)

Answer 3
