Given the following image, which expression correctly defines the purple shaded area? AU(BC)BC Given the following image, which expression correctly defines the purple shaded area? CAB A+B+C ABC BC Which of the following is the Cartesian product of sets A and B where A={a,b} and B={1,2,3} ? {(a,1,2,3),(b,1,2,3)} {(1,a),(a,2),(3,a),(b,1),(2,b),(b,3)} {(a,1),(a,2),(a,3),(b,1),(b,2),(b,3)} There is no Cartesian product because the sets are two different sizes
