    no that is the 'multiplication principle' which says if i can do one thing n ways and another thing m ways then the number of way i can do them both is n times m

    think that you have seven slots in which to put 7 items. you have 7 choices for the first one. so far 7 ways

    now one brand is used and so you have 6 choices for the next slot. so far 7*6

    now you have 5 choices for the fifth slot, 4 choices for the 4th etc. and you have to multiply all these together by the multiplication principle

    answer is \[7\times 6\times 5\times 4\times 3\times 2 \times 1\]
