A province is one of the pilot provinces for the high school new curriculum reform. According to the regulations, every student must participate in the academic level test, and all subjects must be passed to graduate. Those who fail can take a retest. In a certain school, there are 50 students participating in the physics, chemistry, and biology level retest. The probability of retesting only physics is $\frac{9}{50}$, only chemistry is $\frac{1}{5}$, and only biology is $\frac{11}{50}$.
