Question

Given A = {1, 2, 3, 4, 5} and B= {2, 4, 6, 8, 10}, what is A ∩ B?

Answer 1

Just a quick question, what does the N mean again?? (between the a and b)

Answer 2

A intersection B
so basically rewrite both A and B into one roster list, not two

Answer 3

haha, I said that backwards, just write out the numbers that occur in both sets ^_^ into a new set

Answer 4

Oh right, got it. {1, 2, 3, 4, 5, 6, 8, 10} I believe that is the answer...

Answer 5

A = {1, 2, 3, 4, 5}
B= {2, 4, 6, 8, 10}
they both have a 2, and a 4

Answer 6

I think it's {2, 4} they are doubled.

Answer 7

Yeah what @DemolisionWolf said.

Answer 9

the union of sets A and B would equal:
1,2,3,4,5, 10, 4, 6, 8

Answer 10

Oh I see, I was confused Demolision... sorry I gave the wrong answer.

Answer 11

this is an intersection, not a union ^_^ btw

Answer 12

Don't worry @Neon_Green thanks for your effort c:

Answer 13

Ur welcome :D

Answer 14

oh crap my fault read it wrong its not a union its the n and not the u lol im dumb forget my answer

Answer 15

U is for union, so you write all the numbers from both sets into one set
∩ is for intersection, so you write only the numbers that appear in both sets.

^_^

Answer 16

yeah @DemolisionWolf just realized the question is asking fro an intersection adn not a union lol

Answer 17

Hey, but at least you would've gotten it right if it was a union so c:

Answer 18
