我以前用过的一个程序 你试试

Dim a(6) As Integer '声明数组

Function JC(n As Integer) As Double

'求阶乘

JC = 1

For i = 1 To n

JC = JC * i

Next

End Function

Sub S36_7()

'选号

On Error Resume Next

For i = 0 To 6

Line1:

a(i) = Fix(Rnd * 36) + 1

For j = 0 To i - 1

If a(i) = a(j) Then

GoTo Line1

End If

Next

Next

End Sub

Sub PrintNum()

'输出

For i = 0 To 6

Print a(i)

Next

Print

End Sub

Private Sub Command1_Click()

'调用

Call S36_7

Call PrintNum

End Sub

Private Sub Command2_Click()

'输出

Print "获奖概率"JC(36) / JC(7) / JC(36 - 7)

End Sub
