Answer 21

Do you mean: \[\left(\begin{matrix}2012 \\ 2011\end{matrix}\right)\] ?

Answer 22

yes

Answer 23

A binomial coefficient
\(\left(\begin{matrix}n \\ r\end{matrix}\right)\)
is defined as
\(\dfrac{n!}{(n-r)!r!}\)
So substitute the numbers and find your answer.

Answer 24

yes but after that wat

Answer 25

i can do that its just i dont know what to do after

Answer 26

You will need to substitute n=2012, r=2011, and calculate your answer, choose from the choices.

Answer 27

ok so D then considering they be nothing i else i tihnk

Answer 28

im thinking d

Answer 29

cant be 2011 or 2012

give me one sec

Answer 32

@mathmate i did it but then wat

Answer 33

what do you do with the extra 2011

Answer 34

HELP!!!

Answer 35

\[\left(\begin{matrix}n \\ k\end{matrix}\right)=\left(\begin{matrix}n \\n- k\end{matrix}\right)\\so\\\left(\begin{matrix}2012 \\2011\end{matrix}\right)=\left(\begin{matrix}2012 \\2012-2011\end{matrix}\right)=\\ \left(\begin{matrix}2012 \\ 1\end{matrix}\right)=2012\]

Answer 36

really 20212 i thought 1

Answer 37

\[\left(\begin{matrix}2012 \\ 1\end{matrix}\right)=\frac{2012!}{1! *2011!}=\\\frac{1*2*3...2011*2012}{1! (1*2*3...2011)=2012}\]
