Answer:
(a) 0.000000373248
(b) 0.999999626752
Step-by-step explanation:
The aircraft works when at least one of its components works
Probability of failure, f=0.0072
Probability of success, s=1-0.0072=0.9928
(a)
P(all three components fail)=
probability==0.000000373248
(b)
Probability (at least one of the components does not fail)=1-P(all three components fail)
Probability=
Probability=1-0.000000373248=0.999999626752
