Question

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.

I REALLY need an explanation on how to solve this problem, the instructors suck at their job of explaining the math


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?

Answer 1

In case if you need a diagram

Answer 2

B. 9/33

Answer 3

Sorry, but I need to know how to get that, I am just burning out from failing to understand a lot of this
