The lengths of metal strips produced by a machine process are normally distributed with a mean length of 50 cm and a standard deviation of 5 cm. Giving your answer to 4 decimal places, find the probability that the length of a randomly selected strip is: a. Shorter than 46 cm b. Longer than 55 cm c. Between 38 cm and 59 cm

A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 244.8-cm and a standard deviation of 0.9-cm. For shipment, 17 steel rods are bundled together. Find the probability that the average length of a randomly selected bundle of steel rods is between 244.4-cm and 244.5-cm. P(244.4-cm < M < 244.5-cm)
