Answer:
There are 60 different summer reading lists possible.
Step-by-step explanation:
A certain school district has specified 5 different novels and 4 different non-fiction.
Each summer reading list must have exactly 3 novels and 2 non-fiction books.
So, the number of different summer reading lists that are possible is given by:
[tex]5C3\times 4C2[/tex]
= [tex]\frac{5!}{3!2!} \times\frac{4!}{2!2!}[/tex]
= [tex]10\times6=60[/tex]
Hence, there are 60 different summer reading lists possible.
