WebExponential Distribution The continuous random variable X follows an exponential distribution if its probability density function is: f ( x) = 1 θ e − x / θ for θ > 0 and x ≥ 0. Because there are an infinite number of possible constants θ, there are an infinite number of possible exponential distributions.
