(adsbygoogle = window.adsbygoogle || []).push({}); I was thinking that I could solve this with combinations. However, I am unsure of how to use it in this case. If I remember correctly, the combinations are given by: How many sequences are there consisting of seven 0's and three 1's? Example: 0101010000

[tex]\begin{pmatrix}n \\ r\end{pmatrix}=\frac{n!}{r!\,\left(n-r\right)!}[/tex]

Hmm. Any thoughts on this? Am I on the right track with the above?

Thanks.
