Let X have a Poisson distribution with mean of 4. Find a) P(2 <X <5) b) P(X ≥ 3) c) P(X < 3)
Added by Brandon G.
Step 1
The probability mass function (PMF) for a Poisson distribution is given by: P(X = k) = \frac{e^{-\lambda} \lambda^k}{k!} where λ is the mean (in this case, 4) and k is the value we want to find the probability for. So, for X = 3: P(X = 3) = \frac{e^{-4} Show more…
