Two machines produce a certain item. The capacity per day of machine 1 is 1 unit and that of machine 2 is 2 units. Let (X1, X2) be the discrete random variable that measures the actual production on each machine per day. ...Let X be a discrete random variable, with probability Distribution And P(X = x2) = ¾. (a) Determine x1 and x2, such that E(X) = 0 and variance (X) = 10. (b) Sketch the CDF of X. Consider the following network. Assume that each component is independent with probability pi of performing satisfactorily. (a) Find all the minimal paths and cuts. (b) Compute the exact system reliability, and evaluate it ...Find the reliability of the structure function given in Prob. 25.1-2 when each component has probability pi of performing successfully and the components are independent. Consider a harbor with a single dock for unloading ships. The ships arrive according to a Poisson process at a mean rate of λ ships per week, and the service-time distribution is exponential with a mean rate of μ ...Post your question
