In the mass production of a certain piece of a machine, the average length is 25.00 cm and the standard deviation is 0.02 cm. Calculate the probabilities for the following cases:
(a) The length of the piece is less than 25.02 cm.
(b) The length of the piece is between 24.95 and 25.05 cm.
(c) If the manufactured pieces with length deviations of more than 2 standard deviations are rejected, what percentage of the products will be rejected?
