Exponential Distribution The Poisson distribution defines a random variable as the number of flaws along a length of wire (flaws per mm). The exponential distribution defines a random variable as the interval between flaws (mm's between flaws - the inverse). Poisson distribution = # of events that occur in an interval of time Exponential distribution = the time between two successive eventsExponentialExamplesApplicatio n
