Occurrence Applications of the Poisson distribution can be found in many fields related to counting:[22]
Telecommunication example: telephone calls arriving in a system.Astronomy example: photons arriving at a telescope.Biology example: the number of mutations on a strand of DNA per unit length.Management example: customers arriving at a counter or call centre.Civil engineering example: cars arriving at a traffic light.Finance and insurance example: number of Losses/Claims occurring in a given period of Time.Earthquake seismology example: an asymptotic Poisson model of seismic risk for large earthquakes. (LomnitRadioactivity example: Decay of a radioactive nucleus.
The Poisson distribution arises in connection with Poisson processes. It applies to various phenomena of disThe number of soldiers killed by horse-kicks each year in each corps in the Prussian cavalry. This example waThe number of yeast cells used when brewing Guinness beer. This example was made famous by William SeThe number of phone calls arriving at a call centre within a minute. This example was made famous by A.K.Internet traffic.The number of goals in sports involving two competing teams.The number of deaths per year in a given age group.The number of jumps in a stock price in a given time interval.Under an assumption of homogeneity, the number of times a web server is accessed per minute.The number of mutations in a given stretch of DNA after a certain amount of radiation.The proportion of cells that will be infected at a given multiplicity of infection.The arrival of photons on a pixel circuit at a given illumination and over a given time period.The targeting of V-1 flying bombs on London during World War II.[24]Gallagher in 1976 showed that the counts of prime numbers in short intervals obey a Poisson distribution pr
