A company manufacturing electronic components for home entertainment systems buys electrical connectors from three suppliers. It buys 22% of the connectors from supplier A, 36% from supplier B, and 42% from supplier C. It finds that 1% of the connectors from supplier A are defective, 2% of the connectors from supplier B are defective, and 4% of the connectors from supplier C are defective. If a customer buys one of these components and finds that the connector is defective, what is the probability that it came from supplier B?
