Binomial Cumulative Distribution

Menu: [Distribution]-[Binomial CD]

Description: This command calculates the probability the random variable that follows a binomial distribution will fall between given upper bound and lower bound values. For example, it can be used to determine the probability a test with a success probability of 0.5 (50%) that is performed ten times will be successful at least three times but no more than five times.

Definition of Terms

Lower : lower bound (Lower Upper integer)

Upper : upper bound (Lower Upper integer)

Numtrial : number of trials n (integer, n 1)

pos : probability of success p (0 p 1)

Calculation Result Output

prob : binomial cumulative probability
