The fracture strength of a certain type of manufactured glass is normally distributed with a mean of 575 MPa with a standard deviation of 17 MPa.
a) What is the probability that a randomly chosen sample of glass will break at less than 575 MPa?(Round your answer to 4 decimal places.)
b) What is the probability that a randomly chosen sample of glass will break at more than 586 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 596 MPa? (Round your answer to 4 decimal places.)
