A bag contains 8 red marbles, 7 blue marbles and 5 green marbles. If two marbles are drawn out of the bag, what is the probability, to the nearest 1000th, that both marbles drawn will be green?

Answer 1

P(G)= 5/20 = 1/4 on the 1st draw

P(G) on 2nd marble is 4/19

P(2G) = (1/4)(4/19) = 1/19 = about 5.3% chance
