Permutation and Combination

Permutation and combination are fundamental concepts in mathematics used for selecting and arranging items from a given collection. Permutations are arrangements where the order of the items matters. In Permutations changing the sequence creates a different outcome. For example, the arrangement of people in a line or ranking in a competition is a permutation because the position is important. Combinations, on the other hand, focus on the selection of items where the order is irrelevant, such as choosing a team of players or selecting toppings for a pizza. In combinations, the arrangement of the selected items does not change the outcome.

Difference Between Permutation and Combination

The main difference between permutation and combination is that in permutations, the order of items matters, while in combinations, the order does not matter. Let us look at the table below to better understand the key differences:
Permutation Combination
Used when the order of items is important. Used when the order of items does not matter.
Applicable for items of different types. Applicable for items of the same type.
The value of permutation is always higher because it counts different arrangements of selected items. The value of combination is lower since it only counts selections, not arrangements.
Multiple permutations can be derived from a single combination. Only one combination can be formed from a single permutation.
Formula: nPr = n! / (n−r)! Formula: nCr = n! / r! * (n−r)!
Example: For three items A, B, C, the permutation of two items is: AB, BA, BC, CB, CA, AC. Example: For three items A, B, C, the combination of two items is: AB, BC, CA.

FAQ

When to use permutations and when to use combinations in real-life situations?
Use permutations when the order of items matters, involving both selection and arrangements, such as in rankings. Use combinations when the order does not matter, focusing solely on selections, like in group formations or lottery picks.
What do nPr and nCr represent in permutations and combinations?
The number of permutations of n different things taken r at a time, where repetition is not allowed, is denoted by nPr. The number of combinations of n different things taken r at a time, denoted by nCr.
How does repetition affect the usage of permutations and combinations?
Repetition in permutations allows elements to be chosen multiple times, increasing the number of arrangements. In combinations, repetition enables selecting the same item more than once, allowing for groups with duplicates. Overall, it expands the total possibilities in both cases.
