		This is generalized by the binomial theorem, which allows the exponent n to be negative or a non-integer.
		The binomial coefficients also occur in the formula for the binomial distribution in statistics and in the formula for a Bézier curve.
		This generalization is known as the generalized binomial coefficient and is used in the formulation of the binomial theorem and satisfies properties (3) and (7).

	Coefficient - Wikipedia, the free encyclopedia
		In mathematics, a coefficient is a multiplicative factor of a certain object such as a variable (for example, the coefficients of a polynomial), a basis vector, a basis function and so on.
		Important coefficients in mathematics include the binomial coefficients, coefficients in the statement of the binomial theorem, which can be partially found with Pascal's triangle.
		Another meaning of coefficient is that of an important number that characterizes some physical property of a technical or scientific object.

	The Binomial Distribution
		As a general rule, the binomial distribution should not be applied to observations from a simple random sample (SRS) unless the population size is at least 10 times larger than the sample size.
		The latter expression is known as the binomial coefficient, stated as "n choose k," or the number of possible ways to choose k "successes" from n observations.
		The binomial coefficient multiplies the probability of one of these possibilities (which is (1/2)²(1/2)² = 1/16 for a fair coin) by the number of ways the outcome may be achieved, for a total probability of 6/16.

	Math Forum - Ask Dr. Math
		Usually, binomial expansion is introduced using a construction called Pascal's Triangle, but I prefer to think of it in terms of something called the binomial coefficient, which I'll explain later.
		Is it a coincidence that the (n)th row corresponds to the coefficients of the expansion (x+y)^n?
		In essence, the most common use of binomial expansion is in expression simplification; the expansion is usually done when you expect terms to cancel.

	Binomial Trees, Forests, and Heaps
		If we have labels (keys) on the nodes of a binomial tree, and we impose an ordering property where the parent key is larger than the keys of any of its children, we can construct a heap with a binomial queue.
		Binomial heaps are important because of the efficient way in which two heaps can be merged.
		For example, this same scheme could be used with the binomial heap where the items in the BST store a pointer to the node in the binary tree representation of the heap, rather than indices in the heap array.

		The largest of the binomial coefficients (n choose k) is the middle one, with k = [n/2].
		The sum of the binomial coefficients (n choose k) over all k from 0 to n is 2^n, by the binomial theorem.
		A well-known relation for binomial coefficients states that the sum over the squares of the coefficients (n choose k), from k=0 to k=n, is equal to the coefficient (2n choose n).

		Is there is a natural definition of a "2-adic binomial coefficient", B, so that for any 2-adics integers n,k, nBk is a 2-adic integer which is odd iff the generalized Lucas condition holds?
