International Olympic Committee (IOC), these standings are usually compiled for

1. If the top ten nations were randomly selected to march, one after another, into the stadium at the closing ceremonies, in how many ways could the nations have marched in?

2. Assume that the medals won by the Netherlands were won by twenty-five different athletes. These athletes are selected to compete in a contest for charity. Their names will then be listed on a plaque with the athletes who place first, second, and third listed before the others. How many different ways are there to list the top three athletes’ names on the plaque?

3. Assume that the gold medals won by Australia were won by sixteen different athletes. Following the Olympics, a parade of the Australian Olympic participants was held in Sydney. The gold medal winners marched at the head of the column, with four of the sixteen medalists carrying the Australian flag in the front row. If the arrangement of the four gold medal winners in the front row isn’t important, how many combinations of these four athletes are there?
