Example #2: A particular SDSU student takes the trolley to campus 40% of the time and drives his car otherwise. When he takes the trolley, he's on time to his T-Th 8:00 Stat 119 class 90% of the time. If the student drives, his ontime rate drops to 70%. Let A be the event that the student takes the trolley to campus. Let B be the event the student is on time to his Stat 119 class. a) Draw a tree diagram below: use correct notation to label events and ll in all appropriate probabilities (including intersections) P(B|A) _\\P(B|A) P (B |A) P(A) /'__ P (B| A\") > P (A and B) P (A) > P (A and 3) _., P (AC and B) _, P (AC and 3) b) What is the probability that the student is on time to his T-Th 8:00 Stat 119 class? c) What is the probability that this student drove to SDSU, given that he was late to his T-Th 8:00 Stat 119 class? d) The events \"takes the trolley\" and \"is on time to his Stat 119 class\" are: A. disjoint and independent B. joint and independent C. disjoint and dependent D. joint and dependent 60
