Question

A bag contains 4 red marbles, 8 blue marbles and 3 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 red?

Answer 1

4 Red + 8 Blue + 3 Green = 15 Total Marbles

(4/15) * (3/14) * (2/13) = 0.0087912088

Nearest 1000th = 0.009

Answer: 0.009
