Solved problems on exponential distribution
WebExponential Distribution A continuous random variable X whose probability density function is given, for some λ>0 f(x) = λe−λx, 0 <∞ and f(x) = 0 otherwise, is said to be an exponential random variable with rate λ. For X ∼Exp(λ): E(X) = 1λ and Var(X) = 1 λ2.
