Recall Problems 2.2.11, 2.3.17, and 2.4.13 concerning the resistance of an electrical component. Suppose that five of the components are used in an electrical circuit so that the total resistance is the sum of the five individual resistances. Furthermore, suppose that it is reasonable to assume that the resistances of the live components are independent of each other. What will be the expected value and the standard deviation of the total resistance?
