<PRE><B>Question 895191</B>
General rule: n P 0 = 1 and this is true for any positive integer n.


So, 8 P 0 = 1


-------------------------------------------------------


Using the formula


n P r = 8 P 0


n P r = (n!)/(n-r)!


8 P 0 = (8!)/(8-0)!


8 P 0 = (8!)/(8!)


8 P 0 = 1</PRE>
