Question

If you can't read the numbers they say 8. p. 0

Answer 1

The rule of the permutation is

`\text{nPr}=(n!)/((n-r)!)`

From the given picture we need to find 8P6, then

n = 8

r = 6

`\begin{gathered} 8P6=(8!)/((8-6)!) \\ 8P6=(8!)/(2!) \\ 8P6=(8*7*6*5*4*3*2*1)/(2*1) \\ 8P6=20160 \end{gathered}`

8P6 = 20160

If it is 8P0, then

n = 8

r = 0

`\begin{gathered} 8P0=(8!)/((8-0)!) \\ 8P0=(8!)/(8!) \\ 8P0=1 \end{gathered}`

8P0 = 1
