WorksheetFunction.Permut Method
Returns the number of permutations for a given number of objects that can be selected from number objects. A permutation is any set or subset of objects or events where internal order is significant. Permutations are different from combinations, for which the internal order is not significant. Use this function for lottery-style probability calculations.

Syntax
'Declaration
Function Permut ( _
Arg1 As Double, _
Arg2 As Double _
) As Double
'Usage
Dim instance As WorksheetFunction
Dim Arg1 As Double
Dim Arg2 As Double
Dim returnValue As Double
returnValue = instance.Permut(Arg1, Arg2)
double Permut(
double Arg1,
double Arg2
)
Parameters
Arg1
Type: System.DoubleNumber - an integer that describes the number of objects.
Arg2
Type: System.DoubleNumber_chosen - an integer that describes the number of objects in each permutation.
Return Value
Type: System.Double
Remarks
Both arguments are truncated to integers.
If number or number_chosen is nonnumeric, Permut returns the #VALUE! error value.
If number ≤ 0 or if number_chosen < 0, Permut returns the #NUM! error value.
If number < number_chosen, Permut returns the #NUM! error value.
