If we are watching buses pass by in a Poisson process with buses arriving at the average rate of 10 per hour, then what is the probability (to three decimal place accuracy) that between 3:06pm and 3:24pm we see less than 5 buses?
A turnpike toll area contains four toll booths arranged in parallel. The arriVing vehicles conformto the Poisson distribution, with an average headway of 12 s. Assuming that the average service, time is 5 s, the service time is negative- exPonential, and the_ queue discipline is FIFO, find theaverage queue length and the expected time in the system if (1) two of the booths are in operationand (2) Only one booth is open
On the average, a grocer sells three of a certain article per week. Howmany of these should he have in stock so that the chance of his running out withina week is less than 0.01? Assume a Poisson distribution.
Suppose that the number of drivers who travel between a particular origin and destination during a designated time period has a Poisson distribution with parameter μ = 20 (suggested in article "Dynamic Ride Sharing: Theory and Practice," J. of Transp. Engr., 1997: 308-312). What is the probability that the number of drivers will: (i) Be at most 10? (ii) Exceed 20? (iii) Be between 10 and 20, inclusive? (iv) Be strictly between 10 and 20?
Workers at Lyman Limited arrive at work at an average rate of 8 workers per hour. Assuming the arrival times follow a Poisson distribution, calculate the probability that a manager will observe: a) exactly 6 workers arriving in a given hour. b) at least 2 workers arriving in a 15-minute period.
A company has 8000 arrivals of Internet traffic over a period of 17,460 thousandths of a minute. Let the random variable x represent the number of such Internet traffic arrivals in one thousandth of a minute. It appears that these Internet arrivals have a Poisson distribution. If we want to use the formula P(x)= μx•e−μ x! to find the probability of exactly 3 arrivals in one thousandth of a minute, what are the values of μ, x, and e that would be used in that formula?
Suppose that trees are distributed in a forest according to a two-dimensional Poisson process with parameter α, the expected number of trees per acre, equal to 80.a. What is the probability that in a certain quarter-acre plot, there will be at most 16 trees?b. If the forest covers 85.000 acres, what is the expected number of trees in the forest?c. Suppose you select a point in the forest and construct a circle of radius .1 mile. Let X = the number of trees within that circular region. What is the pmf of X? [Hint: 1 sq mile = 640 acres.)
