Question

Question Help 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 it to a safe level. Assume that each surge protector has a 0.94 probability of working correctly when a voltage surge occurs. Complete parts (a) through (c) below PTV Sernies Configuration Parall Parallel Configuration a. If the two surge protectors are arranged in series, what is the probability that a voltage surge will not damage the teleision? 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) c. Which arrangement should be used for better protection O The parallel arrangment provides better protection because it has a lower probability of protection 0 The parallel arrangment provides better protection because it has a higher probability of protection O The series arrangment provides better protection because it has a higher probability of protection O The series arrangment provides better protection because it has a lower probability of protection.

Explanation / Answer

a) The probability that a voltage surge will not damage the television is 0.94*0.94 = 0.8836 since series configuration
b) The probability that a voltage surge will not damage the television is 1 - (1-0.94)*(1-0.94) = 0.9964 since parallel configuration
c) Correct answer: Option (B) The parallel arrangement provides better protection becasue it has a higher probabilty of protection
