Question

Let set A = {1, 3, 5, 7} and set B = {1, 2, 3, 4, 5, 6, 7, 8}.

Which notation shows the relationship between set A and set B?

Answer 1

A ∪ B
A ⊆ B
A ∩ B
B ⊆ A

Answer 2

Ive never been good at this so if someone can help me i would appreciate it, Thanks. :)

Answer 3

I can only do the first and third one.. I"m kind of idiotic for 2 and 4.. maybe I can try (can't guarantee if it's right)

Answer 4

so for the first one A ∪ B this is the union of A and B which means all elements are considered.
For the third one A ∩ B this is the intersection of A and B which means what does A and B have in common and you list those elements only

Answer 5

Try explaining as best as possible. Im trying to learn this and move on. Thank you :)

Answer 6

A subset of B and B subset of A might only return a true or false

Answer 7

A ⊆ B This means A is contained in B...or A is a subset in B
I think it's the elements of A is contained in B.

Answer 8

So as you stated, the third one should be correct? Relationship, right?

Answer 9

Similarly
B ⊆ A
means that B is a subset of A.. B is contained in A.. So I'm assuming it's only elements in B that are contained in A.

Answer 10

I have no idea how to handle that term... if "relationship" you mean what do they have in common? Or "relationship" can be subset idkz.

Answer 11

U is a OR relation and ∩ is a AND relation

Answer 12

I think it would be the third option, n. @hba what do you think?

Answer 13

thanks for helping @UsukiDoll It's been a while since i got help like that. :)

Answer 14

all of A r in B so
A is subset from B ,As B is superset

Answer 15

I guess that would be the answer

Answer 16

Thanks you @hba

Answer 17

When did u hit 99? o.O

Answer 18

Long time ago before i left :p

Answer 19

thanks ^^. At least I tried xD. This is set theory but I really hate some of the symbols.

Answer 20

i left in march so XD

Answer 21

well cya later guys

Answer 22

What's your answer?
