Description: This command calculates the probability the 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)nx

(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
