WebIn probability theory, a probability density function ( PDF ), or density of a continuous random variable, is a function whose value at any given sample (or point) in the sample space (the set of possible values taken by the random variable) can be interpreted as providing a relative likelihood that the value of the random variable would be ... In statistics, a normal distribution or Gaussian distribution is a type of continuous probability distribution for a real-valued random variable.
