Best ResponseYou've already chosen the best response.0In principle, Union is like appending elements. However, note in sets, if the elements are the same, only one counts.

Best ResponseYou've already chosen the best response.1So, I was correct!

Best ResponseYou've already chosen the best response.0Does this make sense? Know that sets are unordered sequences with unique elements. @Kash_TheSmartGuy , you do understand that you gave the answer B (intersection) D, not B (union) D, right?

Best ResponseYou've already chosen the best response.0Yeah, it does. I'll give Sh3lsh a fan since he explained it and Kash a medal. Thanks guys.

Best ResponseYou've already chosen the best response.0The response he gave was incorrect. Write that on a test, and you would receive no credit.

Best ResponseYou've already chosen the best response.0But the question is multiple choice, and {3,9} was one of the answer choices. And you got the same answer too

Best ResponseYou've already chosen the best response.0: {3,9} is the INTERSECTION { 3, 1, 4, 11, 3, 6, 9, 12, 15} is the UNION

Best ResponseYou've already chosen the best response.0{3, 9} {3, 1, 3, 4, 9, 11} { } {3, 1, 3, 4, 6, 9, 11, 12, 15} These are the answer choices. You both said {3, 9}.

Best ResponseYou've already chosen the best response.0Find B union D. B: {3, 1, 3, 4, 9, 11} D: {numbers divisible by 3 from 1 to 15} {3, 9} {3, 1, 3, 4, 9, 11} { } {3, 1, 3, 4, 6, 9, 11, 12, 15} This is the full question

Best ResponseYou've already chosen the best response.0I think you should review set operations. One can take the Union of a set. One can take the Intersection of a set. (and more, but that's later) The previous commenter who didn't rectify his mistake found the INTERSECTION of the set. You asked for the UNION of the set. I explained how one could find the UNION and INTERSECTION. https://www.khanacademy.org/math/probability/independentdependentprobability/basic_set_operations/v/intersectionandunionofsets

Best ResponseYou've already chosen the best response.0I'm confused by what you're trying to say. Is the answer {3, 9} or not?

Best ResponseYou've already chosen the best response.0No. But I cannot explain any longer.
