IncorrectYour answer is incorrect.A sample of a radioactive material is studied in a lab. There are 741 gamma ray emissions over 130 seconds.Use the Poisson distribution to find the probability that 1 or fewer gamma rays are emitted in a given second.Do not round intermediate computations, and round your answer to three decimal places.(If necessary, consult a list of formulas.)0.054

Let X be the number of gamma rays emitted per second follow Poisson distribution with Rate of…
