(Round your answer to three decimal places.) (1)) Find the probability that a plant of this species will live longer than 110 days' (Round your answer to three decimal places') (c) Find the probability that a plant of this species will live longer than 73 days but less than 126 days. (Round your answer to three decimal places.) Problem. 16 : The average waiting time in minutes for patients arriving at the Gator Urgent Care between 8:00 am and 11:00 am on a weekday is an exponentially distributed random variable X with probability density function 1 41/13: f(a:) 7 13 a . (a) What is the probability that a patient arriving at the clinic between 8:00 am and 11:00 am will have to wait between 8 and 18 minutes? (Round your answer to three decimal places) (b) What is the probability that a patient arriving at the clinic between 8:00 am and 11:00 am will have to wait more than 15 minutes?
