Question

Evaluate C(8, 8) help

Answer 1

\[ \frac{8!}{8!(8-8)!}\]

Answer 2

That's from the definition of the combination formula

Answer 3

walk me trough the steps please

Answer 4

have you seen \(C(n, r)=\dfrac{n!}{r!(n-r)!}\) ?

Answer 5

no i never learned it im taking online class

Answer 6

ok well that's the formula for \(C(n,r)\).
And
\(n!=n(n-1)(n-2)(n-3)\cdots(3)(2)(1)\)

So example:
\(4!=4(3)(2)(1)=24\)
\(7!=7(6)(5)(4)(3)(2)(1)=5040\)

Other results:
\(1!=1\)
and
\(0!=1\) (defined to be that)

Answer 7

If you have something like \((6-2)!\), then you compute what's in parenthesis first, so \((6-2)!=4!=4(3)(2)(1)=24\)

Answer 8

thank you because the note they wee giving me i could not understand thanks !!!

Answer 9

your welcome :)
