The lengths of metal strips are normally distributed with a mean of 120 cm and a standard deviation of 10 cm. Find the probability that a strip selected at random has a length a) Greater than 105 cm, P(X> 105). b) Within 5 cm of the mean, P(115 < X < 125). c) Strips that are shorter than L cm are rejected. Estimate the value of L, correct to one decimal place, if 9% of all strips are rejected. (P(X
