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
Answer:
<h3> The first: The easiest to solve for is x in the first equation.</h3>
Step-by-step explanation:
To get x from first equation you just need to subtract 4y from both sides.
The rest of variables needs two operations to get variable - subtracting and then dividing.
