A Company Manufacturing Electronic Components

A Company Manufacturing Electronic Components

Can someone help me explain this statistical problem? 3

A company that makes electronic components for my entertainment system buys electrical connectors from three vendors. The company prefers Supplier A because only 1% of the connectors are defective, but Supplier A can only send 70% of the required connectors. The company should also purchase connectors from two other vendors, 20% from Vendor B and the rest from Vendor C. Connector failure rates for B and C are 2% and 4%, respectively. You buy one of these components, and when you try to use it, you find that the connector is bad. What is the probability that the connector is from supplier A? (Tip: Outline a tree).

1% of 70% is 0.7%

B 2% of 20% equals 0.4%

C is 4% of 10%. 4%

Add them and you will get 0.15%

7/15 It is likely that it comes from Supplier A.
