WorksheetFunction.Binom_Dist Method (Excel)

Returns the individual term binomial distribution probability.

Version Information

Version Added: Excel 2010

Syntax

expression .Binom_Dist(Arg1, Arg2, Arg3, Arg4)

expression A variable that represents a WorksheetFunction object.

Parameters

Name	Required/Optional	Data Type	Description
Arg1	Required	Double	Number_s - the number of successes in trials.
Arg2	Required	Double	Trials - the number of independent trials.
Arg3	Required	Double	Probability_s - the probability of success on each trial.
Arg4	Required	Boolean	Cumulative - a logical value that determines the form of the function. If cumulative is True, then the Binom_Dist method 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.

Return Value

Double

Remarks

Use the Binom_Dist method 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, the Binom_Dist method can calculate the probability that two of the next three babies born are male.

• Number_s and trials are truncated to integers.

• If number_s, trials, or probability_s is nonnumeric, the Binom_Dist method generates an error.

• If number_s < 0 or number_s > trials, the Binom_Dist method generates an error.

• If probability_s < 0 or probability_s > 1, the Binom_Dist method generates an error.

• The binomial probability mass function is: where: is COMBIN(n,x). The cumulative binomial distribution is:
