Component fail

There is a 90 percent chance that a particular type of component will perform adequately under high-temperature conditions. If the device involved has four such components, determine the probability that the device is inoperable because precisely one of the four fails.

Correct answer:

p =  70.84 %

Step-by-step explanation:

p1=0.90  C1(4)=(14)=1!(41)!4!=14=4  p2=(14) p141 (1p1)1=4 0.941 (10.9)1=2500729=0.2916  p=100 (1p2)=100 (10.2916)=70.84%
