One quality characteristic for cabinet manufacturers is easy sliding drawers. A drawer is considered easy sliding if it does not get stuck when opened. His- torically, only 2% of the drawers get stuck. Ten drawers are randomly selected from a new lot. Each drawer is tested and all 10 must be easy sliding before the new lot is shipped. a. Find the probability that the lot will be shipped. b. Find the probability that at least one drawer will get stuck. c. Find the expected number of stuck drawers, the variance, and the standard deviation.
