1. Explain in words why the equation {n \choose k} = {n \choose n -k} is true. The equation C(n;k) stands for "n choose k"‚ and represents the number of k length element combinations which can be formed from a set of n elements (order doesn’t matter). This equations also states that the result from the left side of the equations equals the number of combinations not chosen n-k on the right side. This is true because the left side calculates the number of possible ways to create possible combinations
