At a jeans factory, a random quality check found 8 pairs defective and 292 pairs with no problems. How many defective pairs can be expected in the inventory of 3,000 pairs of jeans?

The check found 8 defective pairs out of 300 total pairs (8 + 292), so the defective rate is 8/300. Apply that rate to 3,000 pairs: (8/300) × 3,000 = 80. Therefore, 80 defective pairs are expected.
