A can company reports that the number of breakdowns per 8-hour shift on its machine operated assembly line follows a Poisson distribution with a mean of 1.5.

What is the probability of exactly three breakdowns on the midnight shift?
What is the probability of greater than two breakdowns in one hour?
What is the probability that the time between two successive breakdowns is at most three hours?
If two hours have gone by without a breakdown, what is the probability that a breakdown will occur in the next one hour?

1. If a company can identify times of the day during an 8 hour work shift when accidents are most likely to occur extra precautions can be instituted during those times. A random sampling of the accident report records over the last year at the factory gives the following frequency of occurrence of accidents during the different hours of the work shift. Can it be concluded based upon the data in the table that the proportions of accidents are equal...

A company has 3 machines: A, B, and C. The number of breakdowns per week is distributed Poisson. On average, machine A breaks down .4 times per week, machine B breaks down .45 times per week and machine C breaks down .9 times per week. The probability that there are 2 breakdowns in one week is _____ (round to 4 decimal places).

Action Motor Sports Company uses a machine that can produce 100 razor scooters per hour. The firm operates 12 hours per day, five days per week. Due to regularly scheduled preventive maintenance, the machines will have to be down 5% of the available time. Based on experience with other products produced during preventive maintenance, the firm expects to achieve an efficiency level for the wheels of 95%. Last week's production was 5,640 scooters, some 60 units below effective capacity a....
