Hi guys,

I am a little confused about how to interpret the matrix included in the equation...can someone please write it in a single line not using the matrix for let's say n=3...


Thanks in advance.

That's not a matrix, it's a standard notation for a binomial coefficient:

$$\left(\begin{array}{c}{n \\ k}\end{array}\right) = _nC_k = \frac{n!}{k!(n-k)!}$$

What matrix? Is [itex]\tau[/itex] a matrix? Because [itex]{n \choose k}[/itex] is not a matrix.
 
Thanks so much Mr. Mute..Mr. Mentallic, I thought (n k) is a matrix not tau...sorry...

Thanks so much for the replies...have a good day guys...
