A jar contains 16 marbles, of which 4 are red, 3 are blue, and the rest are yellow. If 2 marbles are to be selected at random from the jar, one at a time without being replaced, what is the probability that the first marble selected will be red and the second marble selected will be blue?	Choose the correct choice from the following:
A) 3/64	B) 1/20	C) 1/16	D) 1/12	E) 1/8
Note that we want the first marble selected to be red and the second marble selected to be blue.   P=4/16*3/15=1/20.   Answer: 1/20.
