Puzzle for September 25, 2008

Today, in 1957 and under escort from the 101st Airborne Division, nine black students entered an all-white high school in Little Rock, Arkansas in response to a Supreme Court ruling in Brown vs Board of Education.

In the spring of 1957, there were 517 black students who lived in the Central High School district. Eighty expressed an interest in attending Central in the fall, and they were interviewed by the Little Rock School Board, which narrowed down the number of candidates to 17. Eight of those students later decided to remain at all-black Horace Mann High School, leaving the "Little Rock Nine" to forge their way into Little Rock's premier high school.

The "Little Rock Nine" is what percentage of the available population?
