Final answer:
To calculate the waiting time for deliveries, shipping records from Richard's Furniture Company are needed. These enable the calculation of the probability of delivery times past 10 a.m., assuming a uniform distribution of delivery times from 10 a.m. to 2 p.m.
Step-by-step explanation:
The question seems to be related to the concept of probability and how it can be exercised when specific conditions are met, such as being presented with shipping records. In the context given, we are interested in calculating the probability related to the time customers wait for deliveries from Richard's Furniture Company. Since the company delivers furniture between 10 a.m. and 2 p.m. uniformly, this would indicate that the delivery times are uniformly distributed over the four-hour period.
To determine the probability of a customer's waiting time, we would need the shipping records indicating the actual delivery times. With that data, we can calculate the probability that a delivery occurred at a specific time past the 10 a.m. start time. This would involve identifying the frequency of deliveries for each hour and calculating the probability based on the uniform distribution.
