[RESOLVED] Permutations & Combinations

[Yunie]

Wait! SO that means, everytime when we are doing the above type of questions or anything that has to do with permutations & combinations question, we have to think of grouping like-terms together (eg. in this case, we group the 'vowels' together) right?

Thanks again.

Aside from the fact that I had overlooked those other cases, Logophobic's logic is more like what you should do. This type of problems should not be solved by writing down all possible cases -usually there are so many you can't anyway. But sometimes it helps understand the problem.
