<h2>Answer:</h2><h2>The probability of choosing a mystery book from the box, replacing it, and then choosing a biography = $\frac{1}{6}$ </h2>

Step-by-step explanation:

A box of old books contains mysteries, biographies, and children’s books.

The number of books in mysteries = 6

The number of books in biographies = 4

The number of books in childrens = 2

The total number of books = 12

The probability of choosing a mystery book from the box = $\frac{6}{12}$

The probability of choosing a biography book from the box = $\frac{4}{12}$

The probability of choosing a mystery book from the box, replacing it, and then choosing a biography = ( $\frac{6}{12}$ ) ( $\frac{4}{12}$ ) ( since it is with replacement)

= $\frac{1}{6}$
