A quality control engineer tests the quality of produced computers. Suppose that 4% of computers have defects, and defects occur independently of each other. Find the following. (Note: For parts A, B, C, set up a numerical expression only; you don't need to evaluate it.) A- The probability of exactly 5 defective computers in a shipment of 20, B- The probability that the engineer has to test exactly 7 computers in order to find the first defective computer, C- The probability that the tenth computer tested is the fourth defective computer, D- The expected number of computers the engineer would need to examine until finding the second defective one. LABEL YOUR ANSWERS AS A, B, ... .
