3. The life of a tire is normally distributed with a mean of 35,000 miles and a standard deviation of 3200 miles. a. What is the probability that a tire will last for exactly 30,000 miles? b. What is the probability that a tire will last for less than 30,000 miles? What the probablity that a tire lasts between 36,000 and 42,000 miles? d. The shortest lasting 20% of the tires would last at most how long? (Include a graph with your work.) 3.
