PDF[dist, x]
gives the probability density function for the symbolic distribution dist evaluated at x.

PDF[dist]
gives the PDF as a pure function.

For continuous distributions, PDF[dist, x]dx gives the probability that an observed value will lie between x and x+dx for infinitesimal dx.

For discrete distributions, PDF[dist, x] gives the probability that an observed value will be x.
