A jar contains 30 marbles. It has 10 red, 6 black and 14 green marbles. Two marbles are drawn, the first is not returned before the second one is drawn. What is the probability that both marbles are green?


P(Both Green) =
14 / 169


P(Both Green) =
91 / 435


P(Both Green) =
7 / 15


P(Both Green) =
49 / 225
