Can someone review with me permutations and combinations? (when their used/their diffrence)

 

[Martin]

quickie:

Perms: Used when a question is about arranging stuff. IE. How many possible ways could 6 pictures be arranged on the wall. (in the case, 6!)


Comb: Used when you talk about combinations. IE, how many different 6 person committees can be selected from 15 people (15 choose 6)

I would also like to review these, because it's been a year since high algebra for me.
