Question

Miss Nestor is randomly passing out books to her students for free reading time. In her book basket, she has 10 mysteries, 8 historical fiction novels, and 2 biographies. If there are 10 students in Miss Nestor's class for free reading time today, which of the following is the best prediction of the number of students who will receive historical fiction novels for free reading time?

Answer 1

The best prediction for the number of students who will receive historical fiction novels is 4.

Step-by-step explanation:

To predict the number of students who will receive historical fiction novels, we need to determine the probability of selecting a historical fiction novel from Miss Nestor's book basket. Out of a total of 10 + 8 + 2 = 20 books, there are 8 historical fiction novels. Therefore, the probability of selecting a historical fiction novel is 8/20, which simplifies to 2/5 or 0.4. Since there are 10 students in the class, we can multiply the probability by the number of students to make the prediction. 0.4 * 10 = 4 students.
