SUMMARY

The discussion clarifies the interpretation of the notation "n choose 2," which represents the binomial coefficient denoted as C(n, 2) or (n 2). This notation is commonly used in combinatorics to calculate the number of ways to choose 2 elements from a set of n elements. The reference to the Wikipedia page on binomial coefficients confirms the mathematical context of the inquiry.

How do you read this, what does this form stand for? I can't type it here but i hope i can explain it. Parentheses n 2 below the n close parentheses.

I assume you mean the http://en.wikipedia.org/wiki/Binomial_coefficient" .

You read it: "n choose 2".
