 P: 7 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.
 HW Helper P: 1,391 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 $\tau$ a matrix? Because ${n \choose k}$ is not a matrix.
