The fracture strength of a certain type of manufactured glass is normally distributed with a mean of 517 MPa with a standard deviation of 11 MPa.
(a) What is the probability that a randomly chosen sample of glass will break at less than 517 MPa? (Round your answer to 2 decimal places.)
(b) What is the probability that a randomly chosen sample of glass will break at more than 532 MPa? (Round your answer to 4 decimal places.)
(c) What is the probability that a randomly chosen sample of glass will break at less than 545 MPa? (Round your answer to 4 decimal places.)
