At a local high school, the probability that a student has a job and a car is 0.18. Jackson wants to find the probability that a student has a car given that they have a job. What additional information does Jackson need to know in order to fine the probability??

Athe total number of students with cars

Bthe total number of students with jobs

Cthe probability that a student has a job

Dthe probability that a student has a car or job

Verified Answer :

D. the probability that a student has a car or job 

The answer would be C. the probability that a student has a job, because it says in the question that Jackson wants to find the probability that a student has a car given that they have a job.

I thought that it was D. 
the probability that a student has a car or job before, but I got it wrong on a quiz. Looking back on it, answer C. makes more sense.
