If the first World Series occurred in 1903 and the Yankees have played in 36 Series as of 2006, what percent of the Series have the Yankees played in since 1903?

Assuming a series was played every year, then there were 20061903+1 = 104 series.
(+1 because you have to count both the first and the last years.)
so, what percent of 104 is 36?
