What are some key words that you need to look for when deciding if the problem is a combination or permutation?

Solution

Permutation reates to arrangement.

Combination realates to choosing .

Order of selection does not matter in combination problems.

Still i would say there are no fixed rules to above.

Eg : Permtation : Consider, four students walking toward their school entrance. How many different ways could they arrange themselves in this side-by-side pattern?

Just look for the word \" arrange\"

Eg : Comination: Picking three team members from a group

Here order doe not matter.
