We have given the 2 by 2 frequency table.

The probability that a randomly selected book is a nonfiction paperback =

(Number of nonfiction paperback books) / Total number of books

= 23 / 69

= 0.3333

The percentage of nonfiction paperback books is 33.33%

Answer: 33.3%

Explanation:

From the given table, the number of books which is a nonfiction paperback =23

The total number of books = 69

Then the probability that a randomly selected book is a nonfiction paperback is given by :-

$\text{P( nonfiction paperback)}=(23)/(69)=0.33333....$

In percent,
$\text{P( nonfiction paperback)}=0.33333.....*33.333\%\approx=33.3\%$

Hence, the probability that a randomly selected book is a nonfiction paperback is 33.3%
