Plain-text version

The mean of a Poisson distribution with parameter λ and that of an exponential distribution with parameter λ are equal (A) for any value of λ (B) for λ = 1 (C) for λ = 0· 5 (D) for no value of λ

Also written as: The mean of a Poisson distribution with parameter lambda and that of an exponential distribution with parameter lambda are equal
