Question

A = {1, 3, 5, 7, 9}

B = {2, 4, 6, 8, 10}
C = {1, 5, 6, 7, 9}
A ∪ B = ?

a ∅
b integers between 1 and 10
c integers from 1 to 10 inclusive

Answer 1

Option c. integers from 1 to 10 inclusive.

Explanation:

The given sets are A = { 1, 3, 5, 7, 9 }

B = { 2, 4, 6, 8, 10 }

C = { 1, 5, 6, 7, 9 }

We have to determine A ∪ B

A ∪ B = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }

Therefore, A ∪ B is the set of all from 1 to 10 inclusive.

option C will be the answer.
