32.4.5 Pascal's Triangle
Core ideaA number triangle where 'each entry is the sum of the two above its shoulders', and every row is precisely the line of coefficients for (a+b)^n
Module goal. Use combination numbers to explain the expansion of (a+b)^n, master the general term and the pattern of the coefficients, and connect it to Pascal's triangle, paving the way for the binomial distribution in the next stage on probability
