Answer:
8P1 = 8
Step-by-step explanation:
<u>Permutation </u>
The number of elements can be selected from a set of elements.
Let r be the number of elements want to select and n be the set of elements.
It can be written as nPr
nPr = n!/(n - r)!
<u>To find 8P1
</u>
n= 8 and r = 1
8P1 = 8!/(8-1)! = 8!/7! = (8 x 7!)/7! = 8
Therefore 8P1 = 8
P(n, r) = n!
