Answer:

[tex]P=\dfrac{n}{n+12}[/tex]

Step-by-step explanation:

Number of non-fiction books = n

Number of fiction books = 12

We need to find the probability of selecting a nonfiction book, in terms of n.

Total no of books = non-fiction books + fiction books

= n+12

Probability = favourable outcomes/total no of outcomes

Here, favourable outcomes = n

So,

[tex]P=\dfrac{n}{n+12}[/tex]

Hence, the probability of selecting a non-fiction is [tex]\dfrac{n}{n+12}[/tex].
