When a computer disk manufacturer tests a disk, it writes to the disk and then test 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 mean 2 = 2 What is the expected number of error per test area? O a. 20 O b. 2 O c. 1.41 O d. 4
