Question
the probability of a car need new brake pads is 0.3. If it does need brake pads the probability of it also needing new brake discs is 0.8. If not the probability of needing new brake discs is 0.3.
Find the probability that the car needs new brake pads given it needs new brake discs.
I have drawn the tree diagram but don't know how I answer the question
