💡 Analysis & Explanation
[Region Identification Strategy]
A complex Venn diagram is solved by applying strict Boolean logic to the overlapping geometrical boundaries.
[Positive Constraints]
The target demographic must be simultaneously inside the 'electricians' circle AND inside the 'architects' circle. The intersection of these two massive circles contains the numerical values 2 and 9.
[Negative Exclusion Clause]
The prompt strictly commands 'but NOT dentists'. Therefore, any number falling within the boundaries of the 'dentists' circle must be ruthlessly eliminated from our subset.
[Final Extraction]
Looking at our subset (2, 9), the number 2 lies inside the dentists' boundary. Stripping it away leaves only the number 9 sitting purely in the dual-overlap zone.
Conclusion
Exactly 9 individuals fit the exact dual criteria.
