Answer 2

Seriously dude, if you keep asking us basic set theory questions.. I shudder to think what's going to happen next.

Answer 3

Let A = {1,2,3}, B = {3,4} and C = {4,5,6}. Find
(i) A × (B∩C)
(ii) (A × B) ∩ (A × C)
(iii) A × (B∪C)
(iv) (A × B) ∪ (A × C)


Why must you type like this?? Lol @bahrom7893
Anyways... I'll only do the first one.
i -A × (B∩C)
So first you want to find where B and C intersect (that's the upside down U). That would be only {4}. So now you have A x {4}, which means you include all the numbers with A and 4, so {1,2,3,4} is your set.

So to sum it up
U = union, include all points included
X = include all points included
Upside down U = intersection, only list points that both sets have.

Answer 4

He is just copy pasting his homework from some site, not even bothering to type it out properly...

Answer 5

*facepalm* @goformit100 If you want me to teach you your stuff, I would be totally fine. But I'm not going to baby feed you answers, kapich?
