Thread: General

What have you tried? Do you know the formula for a binomial coefficient?

From what formula is it? Can't see it clearly.

nCr=n!/((r!)(n-r!)) with this formula you can try it.

Thank you

This formula is the basic formula of probability.It is used if we select some items out of many items.It means we are selecting r items out of n items.

I think it would be like that :

ⁿC_r = n!/{(n-1)! r!}
