In mathematics, the binomial coefficients are the positive integers that occur as coefficients in the binomial theorem. Commonly, a binomial coefficient is indexed by a pair of integers n ≥ k ≥ 0 and is written $${\displaystyle {\tbinom {n}{k}}.}$$ It is the coefficient of the x term in the polynomial expansion of the … See more Andreas von Ettingshausen introduced the notation $${\displaystyle {\tbinom {n}{k}}}$$ in 1826, although the numbers were known centuries earlier (see Pascal's triangle). In about 1150, the Indian mathematician See more Several methods exist to compute the value of $${\displaystyle {\tbinom {n}{k}}}$$ without actually expanding a binomial power or counting k-combinations. Recursive formula One method uses the recursive, purely additive formula See more Binomial coefficients are of importance in combinatorics, because they provide ready formulas for certain frequent counting problems: • There … See more The factorial formula facilitates relating nearby binomial coefficients. For instance, if k is a positive integer and n is arbitrary, then See more For natural numbers (taken to include 0) n and k, the binomial coefficient $${\displaystyle {\tbinom {n}{k}}}$$ can be defined as the coefficient of the monomial X in the expansion of … See more Pascal's rule is the important recurrence relation $${\displaystyle {n \choose k}+{n \choose k+1}={n+1 \choose k+1},}$$ (3) which can be used to prove by mathematical induction that $${\displaystyle {\tbinom {n}{k}}}$$ is … See more For any nonnegative integer k, the expression $${\textstyle {\binom {t}{k}}}$$ can be simplified and defined as a polynomial divided by k!: this presents a polynomial in t with rational coefficients. See more If X ~ B(n, p) and Y ~ B(m, p) are independent binomial variables with the same probability p, then X + Y is again a binomial variable; its distribution is Z=X+Y ~ B(n+m, p): A Binomial distributed random variable X ~ B(n, p) can be considered as the sum of n Bernoulli distributed random variables.
