2. (10 points) The thicknesses of glass sheets produced by a certain process are normally distributed with a mean of u = 3.20 mm and a standard deviation of o = 0.12 mm. (a) What is the probability that a glasssheet is thicker than 3.25 mm? (b) What is the probability that a glasssheet is thinner than 2.75 mm? (d) What is the probability that four glass sheets placed one on top of another have a total thickness greater than 9.50 mm? (e) What is the probability that eight glass sheets have an average thickness less than 3.10 mm?
