What is the value of 7C3?

The value of 7C3, also known as "7 choose 3," is calculated using the combination formula C(n, k) = n! / (k! * (n - k)!). In this case, it would be 7! / (3! * (7-3)!) = 35. This represents the number of ways to choose 3 items from a set of 7 distinct items without regard to the order in which they are chosen.
