Explanation Function qualityControlCheck(int batchSize, double defectRate): Purpose: Simulates the quality control check for a batch of items. Parameters: batchSize: The number of items in the batch. defectRate: The probability of an item being defective. Implementation: Iterates through each item in the batch. Uses a random number to determine if an item is defective based …
