Question

A bag has four green marbles three red marbles and three yellow Marbles what is the probability that you pick a red marble, do not replace it and pick another red marble

Answer 1

Total marbles = 4 + 3 + 3 = 10

Chance of picking a red marble on first pick : 3/10
Chance of picking a red marble on second pick: 2/9

Therefore probability = 3/10 * 2/9 = 6/90 = 2/30 = 1/15

b) 1/15
