Question

What’s the correct answer for this question?

Answer 1

Answer: choice C

Step-by-step explanation:

The union of events A and B, denoted  ∪ , is the collection of all outcomes that are elements of one or the other of the sets A and B, or of both of them. It corresponds to combining descriptions of the two events using the word “or.”

**keep in mind that we don’t write numbers more than once in these sets(choiceB)

so the answer would be

{3,4,5,6,7,8,9}
