An engineering construction firm is currently working on power plants at three different sites. Let A; denote the event that the plant at the site i is completed by the contract date. Use the operations of union, intersection, and complement to describe each of the following events in terms of A1 , A2 , andAg . (a) At least one plant is completed by the contract date. (b) All plants are completed by the contract date. (c) Only the plant at site 1 is completed by the contract date. (d) Exactly one plant is completed by the contract date. (e) Either the plant at site 1 or both of the other plants are completed by the contract date. 1. A1 U A, U A3 2. A1 N A2 N A3 3. (A1 N AG N Ag) U (AfN Az N AG) U (A¡ n Aş N A3) 4. A1 N Ag N Ag 5. Aj U (A2 N Ag3) The correct option below to match each event to the corresponding description is abcde -- 54231 abcde -- 54321 abcde -- 12435 abcde - 12345 abcde - 21435
