Question: Four components, A, B, C, and D, are connected in parallel. Suppose that components A and B have normal failure time distributions with parameters

Four components, A, B, C, and D, are connected in parallel. Suppose that components A and B have normal failure time distributions with parameters μ = 500 hours and σ = 100 hours, whereas components C and D have Weibull failure time distributions with parameters α = .5 and β = 100. Find the reliability of the system at time t = 300 hours.
