A child has 36 blue marbles and 10 red marbles, and he kept they into a bag. If he asks you to pick up 3 marbles, what is the probability that all the 3 marbles will be red?	Choose the correct choice from the following answers:
A) 1/253
B) 2/253
C) 3/253
D) 1/153
E) 2/153
There are 10 red marbles in a group of 36 + 10 that is 46. Thus the probability of picking all 3 red marbles is: (10/46)(9/45)(8/44) = 2/253. The correct answer is 2/253.
