insert a choose statement in latex
February 23rd, 2006 by Lawrence David
if you’re trying to fit a choose statement into an equation in latex, you might be tempted to use nchoosek (as i was). that doesn’t work though.
try this instead:
N \choose{2}
to print the equivalent of “n choose 2.”

I found that useful, thanks.
it didn’t work for me inserting this into a larger equation.
I used {n \choose k} instead.
I used the {n \choose k} and it worked beautifully!!! Thanks!!!
This was useful, thanks. I guessed it would have been \choose{N}{K}, but that would have made too much sense, I guess.
The construction ${n \choose r}$ (that’s the more correct form for $n \choose{r}$, what you gave) is now deprecated; it’s generally better to use $\binom{n}{r}$ or $\dbinom{n}{r}$.
Thanks, just what I was looking for
