Let X, the number of flaws on the surface of a randomly selected boiler of a certain type, have a Poisson distribution with parameter ? = 5. Use the cumulative Poisson probabilities from the Appendix Tables to compute the following probabilities. (Round your answers to three decimal places.) (a) P(X ? 7) (b) P(X = 7) (c) P(9 ? X) (d) P(5 ? X ? 7) (e) P(5 < X < 7)
