A Professor in a research university wanted to know whether his teaching methods work in the real world. To acquire this information, the Professor surveyed the students of that university who took his course and determined whether each student took his course or not and whether a job was offered to the student in the real world. From the information developed, the Professor produced the table of joint probabilities below:

	Job offer	No Job offer
Took course	0.42	0.22
Did not take course	0.08	0.28

Given that a student took his course, what is the probability that he/ she got a job offer?
