Four students are enrolled in RMI 2101 - Morgan has a 3.2 GPA, Ben has a 2.5 GPA, and Charlotte has a 1.5 GPA, and Justin has a 3.6 GPA. All four of them are taking Intro to risk this semester. Remember that GPA is essentially our expected value. Morgan has a variance of 1.1, Ben has a variance of 0.7 and Charlotte has a variance of 0.7, and Justin has a variance of 1.2. Who faces the most risk? You must show the calculation for each student?
