A certain company sends 50% of its overnight mail parcels via express mail service E1. Of theseparcels, 1% arrive after the guaranteed delivery time (denote the event late delivery by L). Supposethat 10% of the overnight parcels are sent via express mail service E2 and the remaining 40% are sentvia E3. Of those sent via E2 only 2% arrive late, whereas 5% of the parcels handled by E3 arrive late.a. Draw a tree diagram for this problem.b. If a record of an overnight mailing is randomly selected from the company’s file, what is theprobability that the parcel went via E2 and was late?c. What is the probability that a randomly selected parcel arrived on time?d. If a randomly selected parcel has arrived late, what is the probability that is was not sent via E1?
