Answer 2

Answer:

The correct option is option d) {15, 25, 35, 45, 55, 65 }

Step-by-step explanation:

A ={ 15, 25, 35, 45, 55, 65 }

B = { 25, 45, 65}

We are ask to find A∪B.

AUB is simply the union of the two set.  To find AUB , we are going to writ the numbers in A and in B without repetition.

AUB = {15, 25, 35, 45, 55, 65}

Therefore the correct option is option d){15, 25, 35, 45, 55, 65 }
