Question

A = {1, 2, 5, 7} B = {3, 4, 6, 7} C = {0, 5, 8, 9} Find A U B U C. A) {0,1,2,3,4,5,6,7,8,9} B) {1,2,3,4,5,6,7} C) {3,4,5,6,7} D) {3,4,7}

Answer 1

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,

$AUBUC = \{1, 2, 5, 7\}U\{3, 4, 6, 7\}U\{0, 5, 8, 9\}\\= \{0,1,2,3,4,5,6,7,8,9\}$

Hence,

A) {0,1,2,3,4,5,6,7,8,9} is the right answer
