A box contains 3 blue marbles, 4 red, 6 green marbles and 2 yellow marbles. If three marbles are picked at random, what is the probability that they are all blue?	Choose the correct choice from the following
A) 1/45	B) 1/29	C) 1/455	D) 2/275	E) 1/495
Given that there are three blue marbles, four red marbles, six green marbles and two yellow marbles.   Probability that all the three marbles picked at random are blue = Â³1/455â‚ƒ/Â¹âµ1/455â‚ƒ = (1 * 3 * 2 * 1)/(15 * 14 * 13) = 1/455   Answer: 1/455
