The hardness of a piece of ceramic is proportional to the ?ring time. Assume that a rating system has been devised to rate the hardness of a ceramic piece and that this measure of hardness is a random variable that is distributed uniformly between 0 and 10. If a hardness in [5,9] is desirable for kitchenware, what is the probability that a piece chosen at random will be suitable for kitchen use?
