Question

4.2.3 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 voitage, the surge protector reduces it to a safe level. Assume that each surge protector has a 0.95 probability of working correcty when a voltage surge occurs. Complete parts (a) through (c) below p-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.)

Answer 1

a)probability that a voltage surge will not damage =1-P(both protector not work) =1-0.05*0.05=0.9975

4.3.24)P(of a positive result)=1-P(none of 4 have bacteria)=1-(1-0.008)⁴ =0.032
