Assume that the distribution of thefts per minute can be approximated by the Poisson probability distribution. a. Calculate the probability exactly three thefts occur in a minute. (Round your answer to 3 decimal places.)Probability b. What is the probability there are five or more thefts in a minute? (Round your answer to 3 decimal places.)Probability c. What is the probability there is two or less thefts in a minute? (Round your answer to 3 decimal places.)
