When a computer disk manufacturer tests a disk, it writes to the disk and then tests it using a certifier. The certifier counts the number of missing pulses or errors. The number of errors on a test area on a disk has a Poisson distribution with A = 0.15. (a) What is the expected number of errors per test area? (b) What percentage of test areas have 2 or fewer errors? Round your answers to two decimal places (e.g. 98.76). (a) The expected number of errors per test area is (b) i % of test areas have two or fewer errors.
