The breaking strength (in pounds) of a certain new synthetic is normally distributed, with a mean of 168 and a variance of 4. The material is considered defective if the breaking strength is less than 164 pounds. What is the probability that a single, randomly selected piece of material will be defective? (Give the answer to two decimal places.) %
