The following circuit operates if and only if there is a path of functional devices from left to right. Let the event/outcome {AB¢DE} denote that device 1, 2 and 4 are functional (uppercase A, B and D respectively) and devices 3 and 5 are not functional (lowercase e and d, respectively). 1 3 4 5 a) Enumerate the outcomes of the sample space consisting of all possible combinations of the five devices. b) How many of those outcomes have the circuit operational?
