Wendy's restaurant has been recognized for having the fastest average service time among fast-food restaurants. In a benchmark study, Wendy's average service time of 2.2 minutes was less than those of Burger King, Chick-fil-A, Krystal, McDonald's, Taco Bell, and Taco John's (QSR Magazine website, December 2014). Assume that the service time for Wendy's has an exponential distribution.  What is the probability that service time is less than or equal to one minute (to 4 decimals)?______    What is the probability that service time is between 30 seconds and one minute (to 4 decimals)?______    Suppose a manager of a Wendy's is considering instituting a policy such that if the time it takes to serve you exceeds five minutes, your food is free. What is the probability that you will get your food for free (to 4 decimals)?______   Comment. The input in the box below will not be graded but may be reviewed and considered by your instructor.  _________________
