This type of activity is required in a mathematics discipline that is known as combinatorics; i.e., the study of counting. Before reading this lecture, you should be familiar with the concept of permutation.. We first deal with combinations without repetition and then with combinations with repetition. A combination with reposition (or repetition) is a combination where each item may be selected any number of times. combinations n+r-1Cr. For a combination replacement sample of r elements taken from a set of n distinct objects, order does not matter and replacements are allowed. Here are the steps to follow when using this combination formula calculator: On the left side, enter the values for the Number of Objects (n) and the Sample Size (r). \(\normalsize Combinations\ with\ repetition\\. 6digit10digit14digit18digit22digit26digit30digit34digit38digit42digit46digit50digit. = 252, For more info on Combinations: https://en.wikipedia.org/wiki/Combination, https://en.wikipedia.org/wiki/Combination.
