Who likes math?
 

Trying to do some homework and my brain is fried. Am I even close here?

There are 8 different statistics books, 6 different geometry books, and 3
different trigonometry books. A student must select one book of each type.
How many different ways can this be done?

Is the answer 8/17 * 6/16 * 3/15

when you do math problems like this, you should ask yourself when you get your answer, 'does this make sense?'

How can you get a fractional number of ways to do something?

8 * 6 * 3

wtf were you dividing by?

I came up with 144 the first time I did it. But since they can only choose one of each book I thought it was wrong. For instance isn't 2 statistics books and 1 geometry book one of the possibilities of the 144? That isn't 1 of each book.
