On a usual day, the company delivers 2000 orders in the local territory, 1500 to the neighboring territory and the rest to outsiders, from a total of 4000 deliveries. 2%, 3% and 6% of the deliveries sent to local, neighboring and outsider regions respectively get returned by customers. a) If a parcel is returned by the customer, what is the probability it was from an outsider region? b) What is the probability of a customer not being from a neighboring territory, if they did not return the parcel?
