Between 6:00 PM and 7:00 PM, 5 mystery novels, 3 non-fiction books, 7 picture books, and 2 science fiction novels were returned to the library. What is the experimental probability that the next book returned to the library is a picture book?
5+3+7+2 = 17 total books.
7 were picture books.
7/17 is the probability that the next book erturned to the library is a picture book.
I hope this helped. :)))
