Question

During the year you must read 3 books for English class. You can choose from a list of 6 books. How many different sets of 3 books can you choose?

Answer 1

Answer: 120

Explanation:

First book and Second Book and Third Book

6 choices x 5 remaining choices x 4 remaining choices = 120

If you want to use a formula:
`(6!)/((6-3)!)=(6* 5* 4* 3!)/(3!)=6* 5*4=120`
