Question

1. 1.Question:Amy is shelving books in a display in the school library. She has4 comic books, 7 horror, & 6 detective and mystery.

how many ways can she arrange the books on the shelf for shelf? explain ( which do u do 7x4x6=168? or use factorials?)

Answer 1

For this problem, you’ll want to use factorials.

First, we’ll find the total number of books:

4 + 7 + 6 = 17 total books

Then, we’ll find the factorial:

17! = 355,687,428,096,000 (Pretty big number, to say the least!)

Hopefully that helps! Have a great day, and take care!
