A company manufacturing electronic components for home entertainment systems buys electrical connectors from three suppliers. It buys 24% from Supplier A, 36% from Supplier B, and 40% from Supplier C. It finds that 2% of the connectors from Supplier A are defective, 4% from Supplier B are defective, and 5% from Supplier C are defective. If a customer buys one of the components and finds that the connector is defective, what is the probability that it came from supplier B?
