Math Problem Statement

Read the combination value directly from​ Pascal's triangle. 9 Upper C 6

Solution

To find the value of 9 \binom{6} directly from Pascal's triangle:

  1. Locate the row corresponding to n=9n = 9 (Pascal's triangle rows are indexed starting from n=0n = 0).
  2. Find the k=6k = 6-th element in this row (elements are indexed starting from k=0k = 0).

The 9 \binom{6} value is 8484, as Pascal's triangle gives the binomial coefficients for each row.
