Notations for PMF & PDF of binomial distribution

Hello everyone (:

I know that in general, PMF is represented by fX(x) & CDF is represented by FX(x). But in the Wikipedia page for binomial distributions, it shows that's a binomial distribution's PMF is represented by f(x; n, p) and its CDF by F(x; n, p). I understand the intention behind using these notations but I find it rather 'informal'. Which one of these is the more precise notation? Can I just go with the general notations for PMFs and CDFs?

Thank you (:

The general notation is f and F. However for particular families of distribution such as binomial, Poisson, or normal, the notation includes parameters specifiying which member of the family is being used.
