CPM Homework Help : CCG Problem 10-85

At the University of the Great Plains the following data about engineering majors was collected:

What is the conditional probability of living on campus, given that you know a student is an engineering major?
Hint (a):
$920$ students are engineering majors. Of those, how many live on campus?
Compare your answer to part (a) to the probability of living on campus.
Hint (b):
Divide the total number of students who live on campus by the total number of students at the university.
Are the two events, {living on campus} and {engineering major} associated? Use the probabilities to explain why or why not.
Answer (c):
Yes. The probability of an engineering student living on campus is much smaller than the probability of a student picked at random living on campus.
