The statistics included vehicles involved in 999 calls (the equivalent of 911 in the United States) and pursuits. Fire service and ambulance vehicles were not included in the figures.
In a report, use the above information to
1. Calculate and interpret the expected number of traffic accidents per day involving vehicles on operational duties.
2. Use this expected value to construct the probability distribution table that lists the probability of 0, 1, 2, . . . , 10 traffic accidents per day. Graph this distribution and summarize your findings.
