You may need to use the appropriate appendix table or technology to answer this question. (a) What is the appropriate probability distribution for x ? Explain how x satisfies the properties of the distribution. x is described by a uniform distribution because the probability of x occurrences is the same for all values of x. x is described by a Poisson distribution because a Poisson distribution describes the probability of x occurrences of the event over a time period. (b) Compute the probability that exactly 5 cars will arrive in the next hour. (Round your answer to four decimal places.) (c) Compute the probability that no more than 4 cars will arrive in the next hour. (Round your answer to four decimal places.)
