Question

Using the Venn diagram given below, find the universal set.

• A. $U$= {1, 2, 3, 5, 6, 9}
• B. $U$= {1, 2, 3, 4, 5, 6, 7, 8, 9}
• C. $U$ = {4, 7, 8}
• D. $U$ = {1, 2, 4, 7, 8}

Answer 1

The correct option is B $U$= {1, 2, 3, 4, 5, 6, 7, 8, 9}

Universal set is the set containing all the elements.
It contains all the elements of set A, set B and the remaining elements in the Venn diagram.
Hence the universal set is $U$= {1, 2, 3, 4, 5, 6, 7, 8, 9}
