Question

Hellp

Answer 1

Are you there?

Answer 2

Yup.

Answer 3

Do you have a teacher?

Answer 4

Nope.

Answer 5

In other words, how are you supposed to learn this stuff?

Answer 6

That's what I am trying to think too. That's why I have an account here right?

Answer 7

So you have no source of information besides asking people on open study? You take an online class and it asks you to answer questions without any instruction?

Answer 8

Yeah it does. Now, instead of wasting time, Would you like to help?

Answer 9

Well, the reason I'm asking these questions is that this question is so ridiculously easy that you should have been able to answer it in 5 seconds (had you studied your lesson) which would have saved you a ton of the time you are so concerned about wasting.
If you can count that is. Because this question is asking you how many elements are in that set.
So instead of wasting time on a trivial question, why don't you read your lesson?

Answer 10

5 elements

Answer 11

Is that right?

Answer 12

So I see you can count.

Answer 13

Lol

Answer 14

So the problem is that you didn't know what n(A) means which you could have easily found out on your own without expecting someone else to do your work for you. Take some responsibility for your own education. Quit depending on others for every little thing. There will be times when you will need help...we all do. This should not have been one of them.

Answer 15

So is 5 the answer?
