How to solve these issues in facebook?

[Curious]

I have the following queries about facebook:

1. In facebook, my friends can see what I post in my timeline. Now I have posted something on a facebook page which I don't moderate. Some of my friends have not 'liked' that page. Can they see that post?

2. When I comment on a facebook post, can my friends see the comment even when they are not following (or 'liked') the poster?

3. Can I 'like' a facebook page without the knowledge of my friends?

2- Yes, your friends can see the comment even when they are not following (or 'liked') the poster...
3- No, you can't 'like' a Facebook page without the knowledge of your friends...
