In analyzing hits by V-1 buzz bombs in World War II, South London was subdivided into regions, each with an area of 0.25 km2. Shown below is a table of actual frequencies of hits and the frequencies expected with the Poisson distribution. ( The Poisson distribution is described in Section 5-5.) Use...

show that if a random variable (x) has a poisson distribution with parameter (lander),i.e. x~p(0) then e(x)=var(x)

Could anyone please suggest on this problem on Poisson Distribution .The problem is that the population in a city is 30000 and that 0.. 1 in each 1000 of the case the accident occurs at random so this is a Poisson Dist. with Lambda = 0.0001*30000=3. One way in which this rate can change is -...

Customer arrive at a two server system at poisson rate 3 per hour.an arrival finding the system empty is equally likely to enter service with either server.an arrival finding one cusomer in the system will enter service with the idele server.an arrival finding two others in the system will wait in...
