Many of a bank's customers use its automated banking machine (ABM). During the early evening hours in the summer months, customers arrive at the ABM at the rate of one every other minute (assume Poisson). Each customer spends an average of 96 seconds completing the transaction. Transaction times are exponentially distributed. Assume that the length of the queue is not a constraint. 1. Determine the utilization of the ABM. (Round the value of "" to the nearest whole number. Round the final answer to 2 decimal places.)

2. Determine the probability that a customer waits five minutes or more in the line. (Round the final answer to 3 decimal places.)
