Acme electronics manufactures MP3 players at three locations. The plant at Omaha manufactures 50% of the MP3 players and 1% are defective. The plant at Memphis manufactures 30% and 2% at that plant are defective. The plant at Fort Meyers manufactures 20% and 3% at that plant are defective. If an MP3 player is selected at random, what is the probability that it is defective?
