So as not to do your work for you, please tell us what you know about the problem. For example, what is A' ?
Also, do you know what  means?
After you tell us what you know or what you think you might do to try to solve it, then we will help.
Note to other tutors: I won't be online for a while to see if gurly691 replies to this. |

I got:
A' ∩ C = {0} ∩ {2,4,6,8,..} = Ø or {} or null set. I just want to be sure I am doing this correctly.... |
