Answer:
90.91% probability that a car needs an oil change given that it has a certain factory defect
Step-by-step explanation:
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this problem, we have that:
Event A: having a factory defect.
Event B: needing an oil change.
The probability that a car has a certain factory defect is 825.
So
The probability that a car has a certain factory defect and needs an oil change is 750.
So
What is the probability that a car needs an oil change given that it has a certain factory defect
90.91% probability that a car needs an oil change given that it has a certain factory defect
