Question
Suppose that a random variable $X$ has a Poisson distribution with $\lambda=3,$ as in Example $1 .$ Compute the probabilities $P_{6}, P_{7}, P_{3}.$
Step 1
Step 1: The probability mass function of a Poisson distribution is given by: \[P(X=k) = e^{-\lambda} \frac{\lambda^k}{k!}\] where $\lambda$ is the average rate of occurrence and $k$ is the actual number of occurrences. Show more…
