Right I am having an issue with the proof to permutation, I really can see the [itex]n-r-1[/itex]
I think the confusion stems because it is in the general term, which throws me a bit, if possible could someone maybe write it in numbers and the underneath write in the general term if not too much trouble. The reason I ask for this is I am trying to understand the binomial expansion, and I have never done permutation or comnations be for, I do understand factorials and how permutation work and combination, but can't get my head around the proof for the formula.
I would like to thank anyone in advance for posting a replie to this post, much appreciated.
