    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
