A bag contains 3 red marbles, 6 blue marbles and 4 green marbles. If three marbles are drawn out of the bag, what is the probability, to the nearest 1000th, that all three marbles drawn will be blue?

Answer 1

The probability will be (assuming non-replacement of the balls) (6/13)(5/12)(4/11) = 120/1716 = .070
