A box of old books contains 6 mysteries, 4 biographies, and 2 children’s books. Which of the following can be used to determine the probability of choosing a mystery book from the box, replacing it, and then choosing a biography?

Probability of choosing a mystery book is 1/2

Probability of choosing a biography book is 1/3

Step-by-step explanation:

Mysteries books = 6

Biographies = 4

Children books = 2

Total books = 12

Probability of choosing a mystery book = no. of mystery books /total no. Books

= 6/12

= 1/2

Probability of choosing a biography book = no. of biography books/ total no. of books

= 4/12

= 1/3

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17
