The life expectancy of a particular brand of tire is normally distributed with a mean of 40,000 and a standard deviation of 5,000 miles. What is the probability that a randomly selected set of tires will have a life of 36,000 to 46,000 miles? Round your answer to 4 decimal places.

The life expectancy of a particular brand of tire is normally distributed with a mean of 60,000 and a standard deviation of 10,000 miles. What is the probability that a randomly selected tire will have a life of at most 80,000 miles? What is the probability that a randomly selected tire will have a life of at least 60,000 miles? What percentage of tires will have a life of 60,000 to 80,000 miles? What is the probability that a randomly selected tire will have a life of exactly 80,000 miles?
