The question I need assistance with is below:
Probability of a massive exposure of a toxic gas is obtained from a Poisson distribution.
That is the rate of occurrence of the exposure, A, is constant in time t, and the number of exposures
follows a Poisson distribution.
a.) What is the probability that no exposure occurs in time t?
b.) If a regulation requires that the probability of a massive exposure be less than 1-in-100 in a 30 years life of a plant
which produces this gas, what is the acceptable rate of occurrence of this exposure?
I need help answering both parts (a) and (b).
