Question: The list shows the results of a study on the use of plus/minus grading at North Carolina State University. It shows the percents of graduate and undergraduate students who received grades with pluses and minuses (for example, C-, A+, etc)
Of all students who received one or more plus grades, 92% were undergraduates and 8% were graduates.
Of all students who received one or more minus grades, 93% were undergraduates and 7% were graduates.
Find the probability that a student is a graduate student, given that the student received a minus grade.
