Assume that each surge protector has a 0 93 probability of working corectly when a voltage surge occurs. Complete parts (a) through (c) below Hep P-TV IV (Dont round ) 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 O The parallelarrangment provides better profection because it has a higher probabity of protection O The senes arrangment provides better protection bec ause it has a lowor probability of protection O The series arrangment provides better protec tion because it has a higher probabity of protection Project 25 Technology Interest Group 5-54 PM EN 017

Explanation / Answer

a) The probability that a voltage surge will not damage the television is 0.93*0.93 = 0.8649
b) The probability that a voltage surge will not damage the television is 1 - (1-0.93)*(1-0.93) = 0.9951
c) Correct answer: Option (B) The parallel arrangement provides better protection becasue it has a higher probabilty of protection
