How many ways can k be chosen from n? That is because \\( \binom {n} {k} \\) is equal to the number of distinct ways \\(k\\) items can be picked from n items. We often say "n choose k" when referring to the binomial coefficient. Each row gives the coefficients to (a + b) n, starting with n = 0.To find the binomial coefficients for (a + b) n, use the nth row and always start with the beginning.For instance, the binomial coefficients for (a + b) 5 are 1, 5, 10, 10, 5, and 1 — in that order.If you need to find the coefficients of binomials algebraically, there is a formula for that as well.
