ECON 101, taken during the first semester of enrollment, is a good predictor of student success for the Weiss College of Business at State U. Of the students who pass the course on the first try, 78.2% complete their degrees within five years. For students who do not pass the course on the first try, only 54.9% complete the degree within five years. The historic pass rate for ECON 101 is 63.2%. Given that a student completed his/her degree within five years, what is the probability the student passed ECON 101 on their first try?
