hmmm...there is some kind of formula. do u have it in ur textbook? it's like n-1, n-2, something like that...!! good luck~
btw.. i don't think u can just multiply them...
ok...it was bugging me so i looked it up: Permutations.
now i have to look again. cuz it's Combinations. sigh~
n!/k!(n-k)!
n = total # of items
k = # of groupings (skirt, blouse, belt, shoes)
30!/4!(30-4)!=
30!/4!(26!) =
30x29x28x27/4x3x2x1 = 27,405

It's been a while since I've done much math but - I think you would multiply 11x9x3x7

If this is your "closet question" then I think you can only solve it by MAKING your outfits. try it. OK?
