Question

用excel在3-11中产生6个数字一组的随机排列组合（数字可以重复），有多少组合？并且把所有的可能列出来

Answer 1

一共有9^6=531441种
如果你需要把所有的可能都列出来
那么给你一段代码，可以在excel中将全部可能在A~F列列出来
但是，因为计算机速度问题以及组合数量的问题，运算时间会很长哦，中途中断可以用pause/break 键停止
Sub Rand_P()
i = 1
For a = 3 To 11
For b = 3 To 11
For c = 3 To 11
For d = 3 To 11
For e = 3 To 11
For f = 3 To 11
Cells(i, 1) = a
Cells(i, 2) = b
Cells(i, 3) = c
Cells(i, 4) = d
Cells(i, 5) = e
Cells(i, 6) = f
i = i + 1
Next
Next
Next
Next
Next
Next
End Sub

Answer 2

每组有9种可能，共6组，所以组合为9^6=531441种

Answer 3

A1=1
B1=1
for i1=1 to 9
for i2=1 to 9
for i3=1 to 9
for i4=1 to 9
for i5=1 to 9
for i6=1 to 9
IF B1=11 THEN
A1=A1+1
B1=1
CELLS(A1,B1)=i1+3 & "," & i2+3 & "," & i3+3 & "," & i4+3 & "," & i5+3 & "," & i6+3
else
CELLS(A1,B1)=i1+3 & "," & i2+3 & "," & i3+3 & "," & i4+3 & "," & i5+3 & "," & i6+3
B1=B1+1
endif

在第一行第15格输入 =counta(a:j) 得出数量

Answer 4

共有9*9*9*9*9*9个 我就不列出来了。
