Organisms are present in ballast water discharged from a ship according to a Poisson process with an average concentration of 10 organisms/m3.

(b) What is the probability that X is less than its mean value by more than one standard deviation? (c) For what amount of discharge would the probability of containing at least 1 organism be .999?
