In a particular high school English class, 6 students are in both the school band and the chorus, 11 students are in the chorus but not the band, 5 students are in the band but not the chorus, and the remaining 4 students are not in either the band or the chorus.  This information is displayed in the 2-way contingency table below

Suppose that you pick a student at random from the class, and you notice that the student you picked  is someone you saw performing in the band last week.  What is the probability that the student is also in the chorus?  (Write your answer as a decimal rounded to 3 decimal places.)
