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?😀
What happened to 3 p.m. GMT it's 7:13 a.m. GMT isn't it? Oh, well, I need to think about this. No number of users makes it slightly harder.😀
I always say that problems will be posted at 03:00 P.M. (GMT +8).
Sorry you're right. I missed the plus 8. It's been one of those days that's taken a toll.😣
So I know it's 64% that use DBuzz. Without the number of users polled I treat it like 64 out of 100.
0.15 use DBuzz+HiveBlog
0.12 use DBuzz+PeakD
I want to exclude the AND
0.15 x 64 = 9.6 users use both
0.12 x 64 = 7.68 users use both
9.6+7.68 = 17.28 of 64 users use both PeakD+DBuzz or HiveBlog+Dbuzz
64 - 17.28 = 46.72 users only use DBuzz
46.72/64 = 0.73 =
73% use DBuzz exclusively
I am tired both physically and of second guessing my math and I need this day to end.😀 Good night everyone. @jfang003 I've had my shot at this problem. Feel free to give your answer if I am wrong,. Thanks.
0.640.12=0.0768
0.640.15=0.096
1.0-0.096-0.0768=0.8272=82.72%
Answer for Day 5 Problem
The data in the problem are inconsistent. 🎯😆
From the poll, there are 64% who use DBuzz, and each of them may or may not be using another Hive dapp. There are 34% (derived from 64%-15%-12%-7%) of all users who are using DBuzz plus at least one other Hive dapp. In total, there are 30% of all users who use DBuzz only, and the percentage of only DBuzz users from those DBuzz users who use at least one other dapp is 46.875% (taken from 30% divided by 64% or 0.64).
However, the solution above assumes that we ignore the inconsistency that there are 7% who use all three dapps, but only 5% who use both PeakD and HiveBlog (and may or may not be using DBuzz). That will result in -2% of users who use both PeakD and HiveBlog but not DBuzz, which is impossible.

Once again I would never have found the solution because the problem had no solution. After awhile I come up with a method that seems to me to work as a solution because of my bias that there should be a solution. Fooled me twice so shame on me.😀
