Binomial probability formula help?
The formula is P(x)=nCx(probability)(1-probability)^n-x......my question is the combination part. Do you take n^x or what to get a number for nCx?

n C x is the combinations symbol
It is the number of ways you can select 'x' objects from a set that has 'n' objects
The formula is
n C x = n! / [(n - x)! x!]
where "!" is the factorial symbol

do you know term factorial(!),if it is 1!=1 2!=2*1 3!=3*2*1 now ncX means n!/(x!*(n-x)!)...
