kBinomial Distribution Binomial Distribution Probability

Menu: [Distribution]-[Binomial PD]

Description: This command calculates the probability that a random variable that follows a binomial distribution will be a given x value. For example, it determines the probability of x successes when the probability of success p-trial is performed

ntimes.

f (x) = nCxpx(1–p)n– x

(x = 0, 1, ·······, n)

p : probability of success

 

 

(0 <p <1)

 

 

n : number of trials

Definition of Terms

x : specified trial (integer from 0 to n)

Numtrial : number of trials n (integer, n >0)

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

Calculation Result Output

prob : binomial probability
