Normal distribution or Gaussian distribution named after Carl Friedrich Gauss is one of the most important probability distributions of a continuous random variable. This probability density function pdf calculator is featured to generate the work with steps for any corresponding input values to help beginners to learn how the input values are being used in such calculations of triangular distribution. In probability theory a probability density function PDF or density of a continuous random variable is a function that describes the relative likelihood for this random variable to take on a given value.

Consider a continuous random variable X with an absolutely continuous CDF F X x. Define the random variable and the value of x. Probability density is a density FUNCTION f X.

Use PDF to determine the value of the probability density function at a known value x of the random variable X. To find the probability that a normally distributed random variable X falls within a range ab we rely on the Z score and use the formula P a X b P a Z b . X 1 distribute as a chi-square random variable with n degrees of freedom.
