Good luck to everyone participating. As I said, I would skip this one. I also have a headache so I am gonna sit by and watch.

Well I am not going to solve everything but I guess I will toss out an answer without any work.
The answer is inconclusive since 7% use all three but only 5% use both PeakD and HiveBlog. If it was 5% using PeakD and HiveBlog but not Dbuzz then it would make sense but the question does not say that. Therefore the information on the question makes sense and we can't calculate an answer.
Maybe you're right. I was thinking a similar thing at first but perhaps my bias that there should always be an answer got to me again.
One way I worked the problem was trying to put it in terms of a Venn Diagram. There are Hive users that use DBuzz and those that don't. It seems to me the 5% that use both PeakD and HiveBlog should be within the non-users of DBuzz. Because of what the question wants solved the users not using DBuzz can be discarded. Within that Venn diagram region of DBuzz users are poll respondents that use either HiveBlog or PeakD or both.
Maybe the wording "...who use DBuzz do not use either HiveBlog or PeakD" is throwing me off but I don't think the 7% who use DBuzz AND HiveBlog AND PeakD count because it seems to me it should be an inclusive OR. If either OR is true than the statement is true. The AND is also logic true.
15% use HiveBlog AND DBuzz NOT PeakD
12% use PeakD AND DBuzz NOT HiveBlog
5% use HiveBlog AND PeakD NOT DBuzz
7%% use HiveBlog AND PeakD AND DBuzz
If a user uses PeakD they aren't part of the answer. If a user uses HiveBlog they aren't part of the answer. Using both or all three isn't part of the answer. The Answer should be in logic: % use DBuzz NOT PeakD NOT HiveBlog
Wait a minute. I asked for a Boolean truth table problem the other day. Is that what this was supposed to be all about?π
