Step 1
25, we can use the formula for the Poisson distribution: \(P(X = 0) = e^{-\lambda} \frac{\lambda^0}{0!} = e^{-\lambda}\). ** Show more…

Let $X$ be a Poisson distributed random variable such that $P[X=0]=0.5$. Find the mean of $X$.
We have provided the parameter of a Poisson random variable, $X .$ For each exercise. a. determine the required probabilities. Round your probability answers to three decimal places. b. find the mean and standard deviation of $X .$ $$\lambda=4.7 ; P(X=3), P(5 \leq X \leq 7), P(X>2)$$
