Binomial coefficient

Summary

The binomial coefficient (nk)\binom{n}{k} is the number of ways to choose kk elements from an nn-element set. These numbers are the coefficients in the expansion of (x+y)n(x + y)^n. The node binomial coefficient gives the precise definition.

What this node needs for W2
  • edge instance_of in: at least two examples (0 of 2)
  • edge not_instance_of in: at least one non-example (0 of 1)
  • edge specializes both: the more general notions and the special cases (0 of 1)

The writing levels say how complete the text of a node is. They do not measure its truth.
