kGeometric DistributionGeometric Distribution Probability

Menu: [Distribution]-[Geometric PD]

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

f (x) = p(1– p)x – 1

(x = 1, 2, 3, ···)

p : probability of success

 

 

(0 < p < 1)

Definition of Terms

x : specified trial (positive integer)

pos : probability of success p (0 < p < 1)

Calculation Result Output

prob : geometric probability
