| Summary: | This lesson is an investigation of Pascal’s Triangle & how it is used to find the coefficients in the expansion of a binomial. Coefficients are also found using combinations.
The relationship is also shown between Pascal’s Triangle and Pathways.
After this lesson, you will be able to:
- complete Pascal’s 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.
- understand and answer questions regarding the number of pathways.
e.g. number of ways to get from A to H or number of paths a pinball can travel
