Question

A librarian is curious about the habits of the library's patrons. He records the type of item that the first 10 patrons check out from the library.

Answer 1

Answer:

$Pr = 0.4$

Step-by-step explanation:

I've added the missing data to answer the question as an attachment;

And the question is to calculate the probability that the next patron checks out a fiction book.

From the attached table, we have:

$Fiction = 4$

$Total = 10$

So, the probability is:

$Pr = \frac{Fiction}{Total}$

$Pr = \frac{4}{10}$

$Pr = 0.4$
