3. Set operations Let A-(1,2,3} and B-(3,4) and let the universal set U-{xIx > 0). The notation c denotes the complement 1. What is the cardinality of A and cardinality of B 2. What is the cartesian product A B. 3. Calculate P(A) 1. Calculatc AnB, AUB, A B. 5. Calculate AC and write in two different ways (set of elements, and then with a set builder). 6. Calculate U - A and compare to AC
