). A company has three types of customer support calls: billing issues (B), technical issues (T), and general inquiries (G). The probabilities of each type of call are 50% as billing issues, 30% as technical issues, and rest are general inquiries. Each type of call may be resolved on the first attempt (R) or require follow-up (F). Given the following probabilities: P[R|B] Probabilities 0.7 P[RT] P[R|G] 0.5 0.9 (a) Find the overall probability that a randomly selected customer support call is resolved on the first attempt. (b) What is the probability that the resolved issue on the first attempt is the billing issue?
