Question 1183336
.


I'd like to add my  2  cents regarding your note,  where you write for a series of  5  permutations 


                    5!*4!*3!*2!*1!*0!



It is written incorrectly.   The number of permutations of  5  items is 


                    5! = 5*4*3*2*1 = 120.



Be accurate,  when you write Math  ( ! )



Every word and every symbol matters . . .
