jagranjosh.com: CBSE Class 11 Mathematics NCERT Solutions: Chapter 7, Permutations and Combinations
In mathematics, a combination is a selection of items from a set that has distinct members, such that the order of selection does not matter (unlike permutations).
When the order doesn't matter, it is a Combination. When the order does matter it is a Permutation. So, we should really call this a "Permutation Lock"! In other words: A Permutation is an ordered Combination. To help you to remember, think " P ermutation ... P osition" There are basically two types of permutation:
These 120 permutations can be divided into groups, such that each group consists of the permutations that represent the same combination. Since we are choosing three people, each group would consist of 6 permutations.
A combination is a way of choosing items from a set (unlike a permutation) when the order of selection doesn't matter. In smaller cases, it's possible to count the number of combinations. A combination refers to the mixture of "n" things taken "k" at a time without repetition.
