A TV has three key components. The reliability of the video circuit is 97.6%, of the audio circuit is 97.6%, and of the screen is 95.7%. If any of the components fails, the TV will not work. What is the probability of the TV not working?

P( TV Not Working) = 1 - P( TV is working) = 1 - ( 0.976 * 0.976 * 0.957 ) = 0.0883
