A = {1, 3, 5, 7, 9}
ki77a [65]

Answer:

Option c. integers from 1 to 10 inclusive.

Step-by-step 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.
