For a parallel structure of identical components, the system can succeed if at least one of the components succeeds. Assume that components fail independently of each other and that each component has a 0.09 probability of failure. Complete
parts (a) through (c) below.
T....
(a) Would it be unusual to observe one component fail? Two components?
be unusual to observe one component fail, since the probability that one component fails,
than 0.05. It
be unusual to observe two components fail, since the probability that two components fail,, is
than 0.05.
(Type integers or decimals. Do not round.)
(b) What is the probability that a parallel structure with 2 identical components will succeed?
(Round to four decimal places as needed.)
