Of those students whose calls are answered immediately, 80% have schedule related issues. Of those students who were followed up the same day, 60% have schedule related issues. Of those students who were followed up the next day, 40% have schedule related issues. Given that a student has schedule related issues, what is the probability that the call is answered immediately?

day, 40% have schedule related issues. Given that a student has schedule related issues, what is the
