Graph probability density function
WebThe mathematical definition of a probability density function is any function. whose surface area is 1 and. which doesn't return values < 0. Furthermore, probability density functions only apply to continuous variables and. the probability for any single outcome is defined as zero. Only ranges of outcomes have non zero probabilities.

The probability density function is defined as an integral of the density of the variable density over a given range. It is denoted by f (x). This function is positive or non-negative at any point of the graph, and the integral, more specifically the definite integral of PDF over the entire space is always equal to one.
