Understanding Permutations vs Combinations | Part 2

This video is the second of two that describes the difference between a permutation and combination. We discuss both intuition and derivation of the formulas.
0:15 how to remember comb/perm
0:40 comparing the two comb/perm
1:28 main takeaway!
1:52 combination formula derivation (through example)
2:38 accounting for lack of order by dividing out
3:15 general combination formula
3:38 comparison between comb / perm formula
3:55 conclusion
Part 1 builds the generic/simple permutation case and the advanced permutation case. Both formulas are derived with an example.
Part 2 shifts to combinations. First, scenarios are discussed on when to use which. Next, the same example from part 1 is extended. Finally, the formula is derived from the permutation formula.
