If electricity power failures occur according to a Poisson distribution with an average of 3 failures every twenty weeks:

a) Calculate the probability that there will not be more than one failure during a particular week.

b) What is the distribution of the time between power failures?

c) What is the probability that the time between two power failures is between 15 and 30 weeks?

d) What is the probability that the time between two power failures is at least 40 weeks given that it has already been 20 weeks since the last failure?

Certain electrical disturbances occur according to a Poisson process with rate 3 per hour. These disturbances cause damage to a computer. a) Assume that a single disturbance will cause the computer to crash. What is the probability that the system will crash in the coming 10 minutes? b) Assume that the computer will survive a single disturbance, but the second such disturbance will cause it to crash. What is, now, the probability that the computer will crash in the coming...

Singapore Power (SP) is the only operator in the domestic electricity market in Singapore. Electricity distribution generally is associated with extremely high economies of scale because of the infrastructure (a nationwide power grid) needed to deliver power to individual households. Using the theory and models of market structure, examine this firm. Should government be worried about any aspect of how a firm under this market structure will perform? What should government do to address such worries?

A certain electric power company maintains that its average rate of critical home electrical power failures is 1.3 failures per day. From analyzes carried out in previous years, it is known that critical failures appear according to a Poisson process. The failure repair team in electrical networks of that company maintains that the failure rate received per day is higher and chooses to make a count of the number of failures reported to it during the month of May to...

Suppose the number of customers arriving at a store obeys a Poisson distribution with an average of λ customers per unit time. That is, if Y is the number of customers arriving in an interval of length t, then Y∼Poisson(λt). Suppose that the store opens at time t=0. Let X be the arrival time of the first customer. Show that X∼Exponential(λ).

Customers arrive at a cafe every 2 minutes on average according to a Poisson process. There are 2 employees working at the bar providing customer service, i.e., one handling customer orders and another handling payments. It takes an average of 1 minute to complete each order (exponentially distributed). Based on the above: f. What are the service time probability density and cumulative distribution functions? g. What percentage of customer orders will be prepared in exactly 2 minutes? h. What are...
