a. what is the probability that a service time is less than or equal to one minute (to 4 decimals)
b. what is the probability that a service time is between 30 seconds and one minute (to 4 decimals)?
c. 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)?
