WebThe exponential distribution can be used to model random variables that have nothing to do with a Poisson process, as the next example illustrates. Example 35.1 (Lifetime of a Lightbulb) The lifetime of a lightbulb (in years) is an Exponential(λ = 0.3) Exponential ( λ = 0.3) random variable. WebJan 7, 2024 · The exponential distribution is commonly used to calculate the time before a specific event occurs. For example, the amount of time (from now) until an earthquake happens has an exponential distribution. The number of large values is decreasing, while the number of tiny values is increasing.
