Question 462768
He's not talking about plotting points he's talking about the Permutation Formula
I currently have the same question posted but here are the formulas... 
I just figured it out XD


1.) {{{P(n,r) = (n!)/(n-r)!}}}

2.) {{{P(n,n) = n!}}}


All right first use the #1 Formula
{{{P(n,r) = (n!)/(n-r)!}}}

Take the problem 

P=(6,6)

and plug it in to the equation
{{{P(n,r) = (n!)/(n-r)!}}}

Apparently 6 is both n and r

so we rewrite the equation as this

{{{P(6,6) = (6!)/(6-6)!}}}

Lets solve the numerator first

Numerator  

{{{(6!)}}}= 720

so {{{P(6,6) = 720/(6-6)!}}}

now we solve the denominator first work in the parenthesis

Denominator: {{{(6-6)!}}}= {{{(0)!}}}

Well 0!=1

so plug that in and the final answer is

{{{P(6,6) = 720/1}}}

and we know anything over one is whole
so 

{{{P(6,6) = 720/(6-6)!}}}= {{{P(6,6) = 720}}}

And your answer is {{{P(6,6) = 720}}}


Good luck and God Bless!
