(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.
