Menu: ��������������������������[Distribution]-[Geometric ��PD�]

Description: This c�ommand c�alc�ulates the probability that a 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 succ��ess

 

 

(0 <p <1)

Definition of Terms

x : spec�ified trial (positive integer)

pos : probability of succ��ess p (0 <p <1)

Calculation Result Output

prob : geometric� probability

Example

Spec�ified trial : 6

Probability of succ��ess : 0.4
