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

1. 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?

2. What is 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.

3. Are the two events, {living on campus} and {engineering major} associated? Why?

   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.
