The electric-vehicle mаnufаcturing cоmpаny Tesla estimates that a driver whо cоmmutes 50 miles per day in a Model S will require a nightly charge time of around one hour and 45 minutes (105 minutes) to recharge the vehicle’s battery (Tesla company website). Assume that the actual recharging time required is uniformly distributed between 90 and 120 minutes. a. Give a mathematical expression for the probability density function of battery recharging time for this scenario. b. What is the probability that the recharge time will be less than 110 minutes? c. What is the probability that the recharge time required is at least 100 minutes? d. What is the probability that the recharge time required is between 95 and 110 minutes?
