Two rebars used in the construction of a gravity-based concrete offshore structure are connected by a coupling. The strength of each rebar under the cyclic loading expected is normally distributed with a mean of 300 MPa and a standard deviation of 30 MPa . (a) Let X denote the strength of a rebar. What is the value of strength X=xf corresponding to FX(x)=0.025 ? (b) It is judged that the strengths of the two rebars are stochastically independent. What is the probability that exactly one of the t
