Re: permutation combination??? confused
Hi soha;
Generally permutations are arrangements where order counts and in combinations order doesn't .
Please post the questions.
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
