A contractor purchases a shipment of 99 transistors. The way the business works is that the contractor will randomly select and test 10 of these transistors, and keep the shipment only if at least 9 of the 10 are in working condition. If we know that overall, 20% of the transistors have defects (and thus not in working condition), then what is the probability the contractor will keep all the transistors?
