Here is my question, I'm very confused. I struggle with word problems. Could someone please point me in the right direction?
A store has 10 identical boxed stereos to store on 3 shelves. How many ways can the boxes be
stored on the shelves if:
(a) there are no restrictions on the number of stereos on each shelf?
(b) the top shelf must have exactly 2 stereos on it?
(c) each shelf must have at least 2 stereos on it?
(d) no shelf can have more than 5 stereos on it?
hmm for question (a)
is 3x 10! correct?
