You've been hired by the Dean of students at a local college. The dean wants to learn more about why students withdraw from their programs prior to completing their degrees. You develop the following.
J = the event that a student leaves the program because of competing job demands
F = the event that a student leaves the program because of competing family demands
Through your research you learn that the probability that the students leaves because of competing job demands is .25, the probability they leave because of competing family demands is .20 and the probability of both is .12.
What is the probability the student leaves for job or family reasons? Show the formula you used to arrive at your answer.
