The expression "10 C D" typically refers to a combination formula, which is mathematically represented as ( C(n, r) = \frac{n!}{r!(n-r)!} ). In this case, it seems like it might be a typo or misrepresentation, as "C" usually denotes combinations and requires two numerical values, like ( C(10, D) ). If "D" is meant to represent a specific number, then you would substitute that value in to calculate the combinations of 10 items taken D at a time.
