Letxbe a poisson random variable with mean 20.a. use the markov inequality to obtain an upperbound on p=p{x ≥ 26}b. use the one-sided chebyshev inequality toobtain an upper bound on p. c. use the chernoff bound to obtain an upperbound on p. d. approximatepby making use of the centrallimit theorem. e. determine p by running an appropriate program.
