Question: The Tesla Model S 85D is an electric car that the manufacturer claims can travel 270 miles on a single charge. However, the actual distance

The Tesla Model S 85D is an electric car that the manufacturer claims can travel 270 miles on a single charge. However, the actual distance depends on a number of factors including speed and whether the car is driven in the city or on highways. Suppose that the distance is a normally distributed random variable with a mean of 200 miles and a standard deviation of 20 miles. An owner of this model intends to travel to a nearby city and return on the same charge. If the total distance is 210 miles, what is the probability that car makes it without running out of power?
