A manufacturing company implemented a new production process to reduce defective fuses. From the old process, it was computed that at least 1 defect costs the company an average of ₱6,500,000.00 per production run. After implementing the new process, suppose a large lot contains 10% defective fuses and four fuses are randomly sampled from the lot. a Find the probability that at least one fuse in the sample of four is defective. b (Continuing from result in item a) in one production run of 500 eighty-unit lots, how much would be the loss if the cost to manufacture one unit is ₱ 335.75? c How much is the difference from the old process? Did the new process effectively reduce the company’s losses
