Can i please get help solving this problem

The article "Expectation Analysis oi the probability nf Failure for Water Supply Pipeslr pmpnsed using the Puisson distribution to madel the number of failures in pipelines of varinus types. Suppose that for oast-imn pipe of a particular length, the expected number of failures is 1 (very close to one ofthe cases considered in the article). Then X, the number nf failures, has a Pnisson distribution with p 1. (Round your answers to three decimal places.) (a) obtain P(X s 5) by using the Cumulative Polsson probabilities table in the Appendix of Tables. time: (b) Determine 9(x = 2) from the pmf formula. Pix = 2) = E Determine P(X = 2) from the Cumulative Poisson Probabilities table in the Appendix of Tables. time: (c) Determine 9(2 5 x s 4). P(25Xso)= (d) what is the probability that Xexceeds its mean value by more than one standard deviation? \\:l You may need to use the eppmpriate table in the Appendix of Tables to answer this question.
