Web37. The formula for computing a k-combination with repetitions from n elements is: ( n + k − 1 k) = ( n + k − 1 n − 1) I would like if someone can give me a simple basic proof that a beginner can understand easily. probability. combinatorics. To recap, P(n,r ), the number of ways to form a permutation of r elements from a total of nis determined by: 1. Forming a combination of r elements out of a total of n in any one of C(n,r) ways 2. Ordering these r elements any one of r! ways. By the multiplication principle, the number of ways to form a … See more Suppose there is a task to do and this task is broken into a total of two steps. The first step can be done in k ways and the second step can be done in n ways. This means that after multiplying these numbers together, … See more Now, use the multiplication principle to derive the formula for the number of combination of r elements taken from a set of n elements. Let P(n,r) denote the number of … See more
