Question: An automatic machine in a manufacturing process is operating properly if the lengths of an important subcomponent are normally distributed with a mean of 118

An automatic machine in a manufacturing process is operating properly if the lengths of an important subcomponent are normally distributed with a mean of 118 cm and a standard deviation of 5.3 cm. A. Find the probability that one selected subcomponent is longer than 120 cm. Probability = B. Find the probability that if 3 subcomponents are randomly selected, their mean length exceeds 120 cm. Probability = C. Find the probability that if 3 are randomly selected, all 3 have lengths that exceed 120 cm. Probability =
