Question
A. Let U= (1.2,3,4.5,6,7,8,9,10,11,12), let A = [4,5,7.8,11). let B = (1,2,4,9), and let C = (7, 8, 9).
1. write down the folloving set in enumerated form: Au (Bn C)
2. Determine the set BXC
3. Write down the set represented by the bit string 101111011010
B. Let A = {a, b, c, d. Let R be the relation on A defined as follows:
R= {{a, a), (a, b), (a, c), (b, b), (b. a), (C, a), (C. c). (d, d)}
State, giving reasons, whether R is reflexive, symmetric, or antisymmetric.
