A librarian has 10 nonfiction and eight fiction books from which to choose the next three book club selections. What is the approximate probability that she chooses a fiction book, then a nonfiction book, then a fiction book?

0.114
0.131
0.686
0.784

For this case we have a total of 10 nonfiction books and 8 fiction books, we are going to assume that the selection is without replacement so then for the first case the probability of select a fiction book is:

For the second selection we have 17 books remaining and the probability of select a nonfiction book is:

For the last selection we have 16 books remaining and the probability of select a fiction book would be:

Sinally since the events are independent the total probability would be:

it’s A

Step-by-step explanation:

did the test

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
