Based off of the hit television show NUMB3RS, this lesson introduces students to permutations, factorials, and counting principle. The lesson is framed in the context of a wedding, in which (at first) people are arranged to sit in a...

Explains the fundamental principle of counting, which is the beginning point for any study of counting techniques such as combinations and permutations.

This lesson focuses on Combinatorics, a branch of mathematics which is about counting. It includes 5 sections: Factorials, Permutations, Combinations, Combinatorics and Pascal's Triangle, and Combinatorics and Probability with examples...

Any time you pick up a well shuffled deck, you are almost certainly holding an arrangement of cards that has never before existed and might not exist again. Yannay Khaikin explains how factorials allow us to pinpoint the exact (very...
