You have two generations of choice. The first is choosing who receives no coat and the second is ordering the rest of the coats. So the answer is 8 x 7! or 8! Hope this helps. |

You could also think of it as each of the 8 people have 8 things to choose from ( no coat, or one of the 7 coats). So in this case, the first person has 8 choices, the second has 7 and so on.. |
