Question 26

+2 marksOne correct option

A factory produces light bulbs. The manufacturer claims that the probability that a randomly selected bulb is defective is 0.1. Ravi suspects that the defect rate is actually higher than claimed. To test this, he randomly selects 10 bulbs from the production line. If two or more bulbs are found to be defective, he rejects the manufacturer's claim; otherwise, he accepts it. Based on the above data, answer the given subquestions.
