# A 500-page book contains 250 sheets of paper. The thickness of the paper used to manufacture the book has mean 0.08 mm and standard deviation 0.01 mm. a) What is the probability that a randomly chosen book is more than 20.2 mm thick (not including the covers)? b) What is the 10th percentile of book thicknesses? c) Someone wants to know the probability that a randomly chosen page is more than 0.1 mm thick. Is enough information given to compute this probability? If so, compute the probability. If not, explain why not.
