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 votage, the surge protector reduces it to a safe level Assume thai each surge protector has a 0.91 probability of working correctly when a voltage surge oocurs Complete parts (a) through (a) below Series Configraion Pralel C a. If the two surge probectors are arranged in series, what is the probabilty that a voltage surge will not damage the television? (Do not round.) Enter your answer in the answer box and then click Check Answer Clear Al ,3 8 9 6 2 3 4 O.Explanation / Answer
The probability that voltage surge will not damage telivision is one minus probability of both p and q fail at a time.
Given probability of working correctly is 0.91 so failure probability is 0.09
Both at a time failure probability is 0.09^2= 0.0081
Therefore required answer is 1-0.0081 =0.9919
