A) {0,1,2,3,4,5,6,7,8,9} is the right answer
Step-by-step explanation:
Given
A = {1, 2, 5, 7}
B = {3, 4, 6, 7}
C = {0, 5, 8, 9}
We hvae to find the union of all thre sets. In union, the elements of involved sets are combined. The repating elements are only written once
So,
[tex]AUBUC = \{1, 2, 5, 7\}U\{3, 4, 6, 7\}U\{0, 5, 8, 9\}\\= \{0,1,2,3,4,5,6,7,8,9\}[/tex]
Hence,
A) {0,1,2,3,4,5,6,7,8,9} is the right answer
