Question 864366: What would be a word problem with an answer of (6 P 6)/2!2!
Answer by jim_thompson5910(35256) (Show Source):
You can put this solution on YOUR website! One possible problem is "How many ways are there to order 6 books where one pair of books are the same and another pair of books are the same. In other words, if you use letters to code each book uniquely, you would have: A, B, C, C, D, D. In this case, order matters"
