Question
The following is a Poisson probability distribution with µ = 0.2. x P(x)0 0.90421 0.08902 0.00603 0.0008The variance of the distribution is ______.
Solution
The variance of a Poisson distribution is equal to its mean. Therefore, given that the mean (µ) is 0.2, the variance of the distribution is also 0.2.
