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

`Pr = 0.4`

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 = (Fiction)/(Total)`

`Pr = (4)/(10)`

`Pr = 0.4`
