A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 212.8-cm and a standard deviation of 0.7-cm. Find the probability that the length of a randomly selected steel rod is less than 214.6-cm. P(X < 214.6-cm) = Enter your answer as a number accurate to 4 decimal places. Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted.
