The Exponential Distribution: Time Between Poisson Events

This 19-minute educational video explores the exponential distribution and its role in quantifying the probability of time intervals between Poisson (rare) events. Learn how to define exponential variables, understand continuous exponential variables, and apply the exponential interval formula. Discover the important "memoryless property" of the exponential distribution through practical examples including lightbulb lifetimes and radioactive decay. The video includes exercises to reinforce concepts and a formal mathematical explanation of memorylessness. Produced at the University of Washington with funding support from the Boeing Company, this lecture by Steve Brunton provides a comprehensive introduction to this important probability distribution.
