(b) What is the probability that a patient would have to wait between 65 minutes and 2 hours? (Round your answer to two decimal places.) (c) Compute the probability that a patient would have to wait over 2 hours. (Round your answer to two decimal places.) (d) Determine the expected waiting time and its standard deviation (in minutes). (Round your standard deviation to two decimal places.) E(X)- min min
