Menu: [Distribution]-[Poisson PD]

Description: This command calculates the probability that a random variable that follows a Poisson distribution will be a given x value.

f (x) = e–μμx

(x = 0, 1, 2, ···)

μ: mean (μ > 0)

x!

 

 

Definition of Terms

x : specified trial (integer, x >0)

μ: mean (μ > 0)
