At Mountain High School, the students were surveyed about their participation in band (B) and track (T). The results of the survey are shown in the Venn diagram. Circles B and T intersect. Circle B contains 24, circle T contains 31, and the intersection contains 9. Number 14 is outside of the circles. Given that a randomly chosen student participates in band, what is the probability that the student also participates in track?
