The probability density function, often denoted as pdf, is a function that describes the probability of finding a random variable within a defined range. The significance of the pdf, f(x), is that f(x)dx is the probability that the random variable x'...

In mathematics, a probability density function (pdf) is a function that represents a probability distribution in terms of integrals. Formally, a probability distribution has density f, if f is a non-negative Lebesgue-integrable function...
