A reputed school when purchasing large shipments of dry erase markers for all its branches. To do this, it follows this acceptance-sampling plan. It randomly selects and tests 40 markers, then accept the whole batch if there are less than two found to be not working. If a shipment has a 2.5% defective rate, find the probability that the school purchases the whole batch of markers. If the school purchases 2000 markers, what are the expected number of defective markers?
