Two shipping services offer overnight delivery of parcels, and both promise delivery before 10 a.m. A mailorder catalog company ships 30% of its overnight packages using service 1 and 70% using service 2. Service 1 fails to meet the 10 a.m. delivery promise 10% of the time, whereas Service 2 fails to deliver by 10 a.m. 8% of the time. Suppose that you made a purchase from this company and were expecting your package by 10 a.m., but it is late. Which shipping service was more likely to have been used?
