Question
Refer to the figure below in which surge protectors p and q are used to protect an expensive high definition television. If there is a surge in the voltage, the surge protector reduced it to a safe level. Assume that each protector has a 0.91 probability of working correctly when a voltage surge occurs. A) If two surge protectors are arranged in series, what's the probability that a voltage surge will not damage the television?Refer to the figure below in which surge protectors p and q are used to protect an expensive high-definition television. If there is a surge in the voltage, the surge protector reduces i to a safe level. Assume that each surge protector has a 0.91 probability of working correctly when a voltage surge occurs. Complete parts (a) through (c) below. p-4-TV Series Configuration Parallel Configuration a. If the two surge protectors are arranged in series, what is the probability that a voltage surge will not damage the television? (Do not round.) b. If the two surge protectors are arranged in parallel, what is the probability that a voltage surge will not damage the television? (Do not round.) G.Which arrangement should be used for better protection? O The parallel arrangment provides better protection because it has a lower probability of protection O The series arrangment provides better protection because it has a lower probability of protection O The series arrangment provides better protection because it has a higher probability of protection. O The parallel arrangment provides better protection because it has a higher probability of protection
Explanation / Answer
A) if they are in series the probability = 0.91 * 0.91= 0.8281
B)if they are in parallel the probability is = 1 - ((1 - 0.91) * (1 - 0.91)) = 0.9919
C) Option-D is the correct answer.
