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 24 probability of failure Complete parts a through c below STEER a Would it be unusual to observe one component fail Two components It be unusual to observe one component fail since the probability that one component fails is than 0 05 It be unusual to observe two components fail since the probability that two than 0 05 components fail is
