Mathematics Homework Help

Mathematics Homework Help. Statistics help with this equation: P(x)=C(n,x)s^xf^n-x

I need someone to explain this to me. I know its for binomial distribution, but I can’t figure out the C or how to plug this into the calculator. I just need someone to explain it to me because I want to know how to do it by hand as well. I have a TI-83
