### Perms & Combs: Pascal's Triangle & Pathways

http://www.mindbites.com/lesson/5092-perms-combs-pascals-triangle-pathways-530 This 86 minute perms & combs lesson is all about Pascals triangle and how it is used to find the coefficients in the expansion of a binomial. Coefficients are also found using combinations. In addition the relationship is also shown between Pascals triangle and Pathways. This lesson will show you how to: - complete Pascals triangle for any value of the exponent in the expansion of a binomial - choose the coefficients in the expansion of a binomial by using combinations - do questions to find the number of Pathways from A to B Sample question: Expand (2x 1)^4 using Pascals Triangle to determine the numerical coefficients. This lesson contains explanations of the concepts and 18 example questions with step by step solutions plus 10 interactive review questions with solutions. Lessons that will help you with the fundamentals of this lesson include: - 125 Multiplication of Polynomials (http://www.mindbites.com/lesson/5063) - 505 Factorial Notation & Linear Permutations (http://www.mindbites.com/lesson/5105) - 510 Linear Permutations With Restrictions (http://www.mindbites.com/lesson/5088) - 520 Combinations Part I (http://www.mindbites.com/lesson/5090)
