SECTION 2 1. A box contains a total of 100 parts that were manufactured on two machines, A and B. 55 parts were manufactured on Machine A. Out of the 100 parts 55 are defective. Of the 55 parts manufactured on Machine A, 22 are defective. Let D be the event that a randomly selected part is defective (and let ND represent not defective). A standard table of total and joint events can be set up as follows: Machine A Machine B Defective (D) Not defective (ND) Total Total
