Professor James believes that students who attends his Statistics class regularly have a higher chance of getting an A in the class. He took attendance for all his classes and discovered that about 88% of statistics students attended class regularly. He also found out that if a student attends class regularly, there is a 38% chance that the student receives an A grade; however, if a student does not attend class on a regular basis, there is only 3% chance of an A grade. If a randomly selected student receives an A grade, what is the probability that the student attended statistics class regularly? Draw a probability tree to solve the problem.
