For all of the countries to do all the sports in the Olympics there has to be a certain amount of them in the team. However it is possible for a country to participate in all of the sports.

There are 29 sports in the Summer Olympics (although only 26 sports will be at the 2012 Olympics). There are 15 sports in the Winter Olympics (all 15 were held at the 2010 Olympics).
