In a university, 40% of students are business majors and 60% of students are not business majors. Given that a student is a business major, then there is 70% chance that he/she will be employed immediately after graduation. Given that a student is a business major, then there is 30% chance that he/she will not be employed immediately after graduation. And if a student is not a business major, then there is a 35% chance that he/ she will be employed immediately after graduation. If a student is not a business major, then there is a 65% chance that he/ she will not be employed immediately after graduation. a. Construct a probability tree for this problem b. Construct a probability table for this problem c. What is the probability that a student is a business major given that he or she is employed immediately after graduation
