Suppose that the time between arrivals of customers at a bank during the​ noon-to-1 p.m. hour has a uniform distribution between 0 and 30 seconds. a. What is the probability that the time between the arrivals of two customers will be less than 14 ​seconds? b. What is the probability that the time between the arrivals of two customers will be between 11 and 19 ​seconds? c. What is the probability that the time between the arrivals of two customers will be greater than 23 ​seconds? d. What are the mean and standard deviation of the time between the arrival of two​ customers?
