To build a component, workers must fit a rod into the hole of a metal ring. the dimensions of the parts can vary a bit due to manufacturing variability. the diameter of the hole follows a normal distribution with a mean of 12 inches and a variance of 0.0484 inches2 . the diameter of the rod follows a normal distribution with a mean of 11.8 inches and a variance of 0.0121 inches2 . what is the probability that a randomly chosen rod will fit into a randomly chosen ring?
