SUMMARY

The discussion focuses on solving a combinatorial problem involving three sets: A, B, and C. The goal is to determine the total number of unique sets that can be formed using elements from each of these sets. Participants suggest starting with a simplified enumeration approach using smaller subsets, such as A = {a1, a2}, B = {b1, b2}, and C = {c1, c2}, before generalizing the findings. This foundational method aids in understanding the combinatorial principles at play, leading to more complex solutions.

PREREQUISITES
  • Understanding of basic combinatorial principles
  • Familiarity with set theory and notation
  • Ability to perform enumeration of small sets
  • Knowledge of generalization techniques in combinatorics
NEXT STEPS
  • Research the principles of combinatorial enumeration
  • Learn about the inclusion-exclusion principle in combinatorics
  • Explore advanced combinatorial techniques such as generating functions
  • Study applications of combinatorics in algorithm design
USEFUL FOR

Mathematicians, computer scientists, and students studying combinatorics or algorithm design who seek to deepen their understanding of set-based problems and enumeration techniques.

Please help me with combinatorics:
I have three sets:
A with elements (a1 ……..ai )
B with elements (b1 ……..bk )
C with elements (c1 ……..cj )

Pls help me to work out how many sets ABC shall I have that contain each element from sets A, B and C

Thanks much

You can try to simplify the problem first by considering something you can do by simple enumeration with A (a1,a2) B(b1,b2) and C(c1,c2). Then you try to generalize your results. Of course there are better ways, fancier etc but at least you have a starting point.
