JEE Advanced Permutations and Combinations Important Questions

The basic difference between Permutation and Combination is following a particular order. While making a selection, if the ‘order of selection’ has no preference, then the formula of ‘Combination’ has to be used. In case, the order of selection has a preference, then the formula of Permutation has to be used. Therefore, Permutation deals with the concept of arrangement, and Combination deals with the concept of selection. Once students are able to distinguish between the concepts of selection and arrangement, solving these sums takes very little time. Download the below PDF and refer to the important questions on Permutation and Combinations for JEE Advanced 2023.

Students are required to know the concept of ‘factorial’ in order to excel in Permutation and Combinations.

• If there are a total of ‘n’ number of options and only ‘r’ number of options are to be chosen, in a particular order without any repetitions, then the following formula of Permutation has to be used.

\[\frac{n!}{(n-r)!}\]

• If there are a total of ‘n’ number of options available and only ‘r’ number of options are to be chosen, without any repetition, and the order of the arrangement is not to be counted, then the following formula of Combination has to be used.

\[\frac{n!}{r!(n-r)!}\]
