BINOMDIST

Description: Returns the individual term binomial distribution probability. Use BINOMDIST in problems with a fixed number of tests or trials, when the outcomes of any trial are only success or failure, when trials are independent, and when the probability of success is constant throughout the experiment. For example, BINOMDIST can calculate the probability that two of the next three babies born are male.

Syntax: BINOMDIST(Number_S, Trials, Probability_S, Cumulative)

• Number_S is the number of successes in trials.

• Trials is the number of independent trials.

• Probability_S is the probability of success on each trial.

• Cumulative is a logical value (True = 1; False = 0) that determines the form of the function. If Cumulative is TRUE, then BINOMDIST returns the cumulative distribution function, which is the probability that there are at most Number_S successes; if FALSE, it returns the probability mass function, which is the probability that there are Number_S successes.

Remarks:

• Number_S and Trials must be an integer.

• Number_S, Trials and Probability_S must be numerical.

• Number_S must be >= 0 and <= Trials.

• Probability must be > 0 and < 1.

• When used in a RENO flowchart, the Number_s, Trials and Probability_S parameters must evaluate to numerical values. They can include:

Example:

• BINOMDIST(6, 10, 0.5, FALSE) = 0.205078
