Answer:

4

Step-by-step explanation:

12÷ 3 (books)=4

Using combinations, 15400 different groups of 3 books are available from the list of 12.

What is combinations?

Combinations are selections made by taking some or all of a number of objects, irrespective of their arrangements.

Given

Total number of books = 12

You are to choose 3 books to read over the summer.

Number of different group of 3 books = [tex]\frac{12C_{3}.(9C_{3}).(6C_{3}).(3C_{3} ) }{4!}[/tex]

= [tex]\frac{\frac{12!}{3!9!} .\frac{9!}{3!6!} .\frac{6!}{3!3!} }{4!}[/tex]

= 15400.

Thus, 15400 different groups of 3 books are available from the list of 12.
