1. LetS= {1,2,3,...,18,19,20} be the universal set. Let setsAandBbe subsets ofS, where: Set A={1,2,3,4,6,7,8,10,12} Set B={1,2,3,4,5,6,7,8,9,10,11}

LIST the elements in Set AandSet B:

LIST the elements in Set AorSet B:

2. The Venn diagram here shows how many elements are in each region. Use this to find the number of elements in the given set. n(A?B^c)
