Use the method of natural frequencies to find the indicated probability.A company manufacturing electronic components for home entertainment systems buys electrical connectors from three suppliers. It buys 23% of the connectors from supplier A, 34% from supplier B, and 43% from supplier C.It finds that 2% of the connectors from supplier A are defective, 3% of the connectors from supplier B are defective, and 5% 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?
