Answer:

[tex]Pr = 0.4[/tex]

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:

[tex]Fiction = 4[/tex]

[tex]Total = 10[/tex]

So, the probability is:

[tex]Pr = \frac{Fiction}{Total}[/tex]

[tex]Pr = \frac{4}{10}[/tex]

[tex]Pr = 0.4[/tex]
