I have come up with the justification as to why the four circle venn diagram does not work and have come up with a few solutions to the problem; I find myself hitting a wall when it comes to justifying why my chosen solutions work. I am not sure if I should just work through every possible combination and justify that it works that way or if I am simply supposed to indicate that the issue found in the four circles is resolved with my solutions. I am struggling to find a middle ground in these options but I can't seem to find one. I was hoping you could push me in the right direction?

hi *******,

I have two questions for you:

1) why do you believe that your solution works?

2) Do you mind If I post your question on the blog, without your name of course?

thanks,

Tom

I believe my solution works in that it bears similar characteristics of the four circle venn diagram but it also has the two combinations that I believe it did not represent. I'm not sure how I could go about strengthening that into a solid argument though.

I don't mind at all!

Thanks,

OK, so referring back to the homework problem, you can see from the hint in part a) that the set (A^D)/(BUC) is missing (I'm constrained in my fonts so I'm using '^' for intersection and 'U' for union), so it would be good if your new sets have this as one of the two new combinations.  So my help to you are questions. Which kind of combinations do you need to consider? How many of these combinations should you have, and how many do you have? (i.e. do you have the right number of combinations?)  How can you label the combinations you should have, and how can you tell if you have them all?
