Suppose an electric-vehicle manufacturing company estimates that a driver who commutes 50 miles per day in a particular vehicle will require a nightly charge time of around 1 hour and 30 minutes (90 minutes) to recharge the vehicle's battery. Assume that the actual recharging time required is uniformly distributed between 70 and 110 minutes.

What is the probability that the recharge time required is at least 79 minutes?

What is the probability that the recharge time required is between 90 and 120 minutes?

what is the probability that the recharge time will be less than 101 minutes?
