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.
