Question

If A = {0, 1, 2, 3} and B = {…−3, −2, −1}, what is A ∩ B?

{…−3, −2, −1, 0, 1, 2, 3, …}

{…−3, −2, −1}

{0, 1, 2, 3}

{ }
Would it be A?

Answer 1

i would say last one d)

Answer 2

no element exist in both sets

Answer 3

so its empty set

Answer 4

Finally. Getting tired of inequalities :D
The intersection of two sets A and B, denoted
A ∩ B
is the set of all the elements they have in common.
DO they have any elements in common? ^.^

Answer 5

So y is it an empty set, I don't exactly get that part

Answer 6

Because they simply have no elements in common :)

Answer 7

So like they have no numbers that are the same?
U and me both r getting tired of inequalites

Answer 8

inequa;ities???

Answer 9

Yes, PRECISELY :)
They have no elements in common :)
Think of it this way
A ∪ B is the set of all elements in A OR B

A ∩ B is the set of all elements in A AND B
