WorksheetFunction.BinomDist Method

Returns the individual term binomial distribution probability.

Namespace:  Microsoft.Office.Interop.Excel
Assembly:  Microsoft.Office.Interop.Excel (in Microsoft.Office.Interop.Excel.dll)

Syntax

'Declaration
Function BinomDist ( _
    Arg1 As Double, _
    Arg2 As Double, _
    Arg3 As Double, _
    Arg4 As Boolean _
) As Double
'Usage
Dim instance As WorksheetFunction
Dim Arg1 As Double
Dim Arg2 As Double
Dim Arg3 As Double
Dim Arg4 As Boolean
Dim returnValue As Double

returnValue = instance.BinomDist(Arg1, _
    Arg2, Arg3, Arg4)

double BinomDist(
    double Arg1,
    double Arg2,
    double Arg3,
    bool Arg4
)

Parameters

• Arg1
  Type: System.Double

  The number of successes in trials.

• Arg2
  Type: System.Double

  The number of independent trials.

• Arg3
  Type: System.Double

  The probability of success on each trial.

• Arg4
  Type: System.Boolean

  A logical value 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.

Return Value

Type: System.Double

Remarks

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.

Number_s and trials are truncated to integers.

If number_s, trials, or probability_s is nonnumeric, BinomDist generates an error.

If number_s < 0 or number_s > trials, BinomDist generates an error.

If probability_s < 0 or probability_s > 1, BinomDist generates an error.

The binomial probability mass function is:

is COMBIN(n,x).
