At a used-book sale, adult books and children’s books are sold. Of the adult books, 70 are nonfiction and 30 are fiction. Of the children’s books, 60 are nonfiction and 100 are fiction. If a book is selected at random,

(a) Find the probability that the book is a children’s book.

(b) Find the probability that the book is nonfiction.

a) 0.6154

b) 0.5

Step-by-step explanation:

We are given the following in the question:

Adult books:

Number of non-fiction = 70

Number of fiction = 30

Total number of adult books =

= Number of non-fiction + Number of fiction

Children books:

Number of non-fiction = 60

Number of fiction = 100

Total number of Children books =

= Number f non-fiction + Number of fiction

Total number of books =

= Number of adult books + Number of Children book

Formula:

a) probability that the book is a children’s book.

b) probability that the book is nonfiction.
