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 0.11 probability of failure.

AWould it be unusual to observe one component fail?
BWould it be unusual to observe two components fail?
CWhat is the probability that a parallel structure with 2 identical components will succeed?
DHow many components would be needed in the structure so that the probability the system will succeed is greater than 0.9999? Round to nearest whole number

Verified Answer :

so the question wants to choose among the following choices that states and support the said question and base on my understanding, I would say that the answer would be letterĀ (d) How many components would be needed in the structure so that the probability the system will succeed is greater than 0.9999? Round to nearest whole num
