So for example if there are 4 red balls and 3 yellow balls in a bag, the probability of choosing a red ball will be 4/7 Exponential Distribution: PDF & CDF. If a random variable X follows an exponential distribution, then the probability density function of X can be written as: f(x; λ) = λe-λx. where: λ: the rate parameter (calculated as λ = 1/μ) e: A constant roughly equal to 2.718. The cumulative distribution function of X can be written as: F(x; λ) = 1 ...Birthday problem.
