Homework Statement
I know what's happening with the problem, but I just hate myself drawing all possible arrangements, I think I am too stupid, I hope better solution.
Problems:
6 different Cookery books and 8 different History books are put on bookshelf. How many possible arrangements if no two cookery books can be put next to each other.
Homework Equations
The Attempt at a Solution
My first approach was to think about the number of arrangements, without considering the difference within the same category of books. C for cookery , H for history
then CHCHCHCHCHCHHH
HCHCHCHCHCHCHH
...
then it comes to a hard time, stupid time, trying to figure out all possiblity by human minds.
It is very easy to make mistakes and very time consuming and hateful...
I think I am too stupid and I don't think it's the solution. Would anyone teach me any other possible solution?
Thanks
