Answer:
The probability that the CMOS module of the computer system functions = 0.9979
Step-by-step explanation:
The CMOS module functions when all 3 components work.
Probability that component A works = 1 - (Probability that component A fails) = 1 - 0.0015 = 0.9985
Probability that component B works = 1 - (Probability that component B fails) = 1 - 0.0005 = 0.9995
Probability that component C works = 1 - (Probability that component Cfails) = 1 - 0.0001 = 0.9999
Probability that the CMOS module functions = probability that all three components work = 0.9985 × 0.9995 × 0.9999 = 0.9979
