![]() ![]() In mathematics, permutation is a technique that determines the number of possible ways in which elements of a set can be arranged. Generally speaking, permutation means different possible ways in which You can arrange a set of numbers or things. It is advisable to refresh the following concepts to understand the material discussed in this article. Permutations with Repetition These are the easiest to calculate. If all of the balls were the same color there would only be one distinguishable permutation in lining them up in a row because the balls themselves would look the same no. It contains a few word problems including one associated with the fundamental counting princip. If there is a collection of 15 balls of various colors, then the number of permutations in lining the balls up in a row is 15P15 15. No Repetition: for example the first three people in a running race. This video tutorial focuses on permutations and combinations. Solving problems related to permutations Permutations There are basically two types of permutation: Repetition is Allowed: such as the lock above. ![]() For example, the permutation defined by () has a 1-cycle, () while the permutation defined by () and () has a 2-cycle () (for details on the syntax, see § Cycle. ![]()
