... are we helping you cheat for a test?......
Martin has a science book, an English book, a geography book, and a history book for school. How many different ways can Martin arrange these books on a book shelf?


A. 24 ways
B. 4 ways
C. 32 ways
D. 12 ways

-
4*6 = 24

-
You have 4 books so 4 possible spots: __ x __ x __ x __

In the first spot you can put any of the 4 books, In the second spot you now only have 3 options because you already put a book in the first spot, then 2 options, then 1.

So you are solving: 4 x 3 x 2 x 1 = 24

-
The answer is 4!, that is: 4*3*2*1 which would equal 24. So, the answer is A

-
Wait..... are we helping you cheat for a test?
