On the shelf, there are three books of poetry, five novels, and eight reference works. Suppose we picked two books at random. What is the probability that we pick one novel and one reference work?  Choose the correct option
A) 1/2
B) 1/3
C) 1/4
D) 1/5
E) 1/6
We could pick one novel and then one reference work, or, we could choose one reference work and then one novel.   P(one novel and one reference work) = 5/16*8/15 + 8/16*5/15 = 1/3   The answer is 1/3.
