Given the set A ={ 1, 2, 3, 4, 5, 6}, B = {2, 3, 6, 7}, C = {3, 6, 9, 10}, show the Venn diagram, and highlight/shade the following (Venn diagram 2 points, shading 2 points each) six points total 61) (AU B)(A C) b) (A B) n (AC) c) For the universal set U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 20}. Express {2, 3, 6, 7} using bit string such that ith location is 0 if the element is missing in the set, and is '1' if it is present. (2 bonus points)
