  Probability Function -- from Wolfram MathWorld
  
  The probability function P(x) (also called the probability density function (PDF) or density function) of a continuous distribution is defined as the derivative of the (cumulative) distribution function D(x),D^'(x)=[P(x)]_(-infty)^x(1)=P(x)-P(-infty)(2)=P
