What are your chances of becoming an Olympic athlete?

This interesting picture (courtesy of eCollegeFinder.org) shows the chances of U.S. athletes making it to the Olympics, looking at the 2008 (Beijing) and 2012 (London) Olympic Games participation data.
High school aged boys have a 1 in 8778 chance of making the U.S. Track & Field Olympic Team. For girls, it’s a bit tougher (1 in 9079), even if the lower possibilities are for basketball players (this is not a surprise for U.S., is it?).
