A. Find the probability that one selected subcomponent is longer than 117 cm. Probability B. Find the probability that if 3 subcomponents are randomly selected, their mean length exceeds 117 cm. Probability C. Find the probability that if 3 are randomly selected, all 3 have lengths that exceed 117 cm.
