    So, 105/7=15 right? Or maybe I misread your equation...

    \[\frac{\frac{15!}{2!13!}}{\frac{7!}{6! }}=15 \] The cobination of 15 things taken 2 at a time divided by 7 things taken 6 at a time?

    So your problem looks exactly like this: \[15c2/7c6\]

  22. anonymous

    Meaning 15c2 divided by 7c6 right?
