# What is the Difference Between Permutation and Combination?

The difference between permutation and combination is that permutation considers order, like arranging letters in a word (CAT vs TAC are different). Whereas, combination focuses on the selection itself, like choosing fruits for a smoothie (apple-banana is the same as banana-apple).

## What is Permutation?

A permutation is like rearranging objects in a line. Order matters! Think decorating: placing a lamp before a plant (lamp-plant) is different from a plant lamp.  This is unlike combinations, where order doesn’t count (picking fruits for a basket).

## What is Combination?

A combination is like picking things for a bag: order doesn’t matter. For instance, picking apple-banana is the same as banana-apple in your lunch bag. The table below lists the definition and examples related to combination to make this concept easier for you.

## What is the Difference between Permutation and Combination

This table provides a clear comparison between permutation and combination based on various aspects such as purpose, order, number of results, representation, formulas, and real-life applications.

## Permutation and Combination Formulas

Permutation and combination are the ways to select certain objects from a group of objects to form subsets with or without replacement. Here we have stated the most important Permutation and Combination Formulas :

## Application of Permutation and Combination Real Life

Real-life applications include password combinations, seating arrangements, lottery numbers, team formations, and arranging books on shelves efficiently. Additional real-life applications of Permutation and Combination are stated below:

• Permutations help with order-dependent choices. Imagine dressing up: if shirt and pants matter (permutation), there are more options than just choosing two clothes (combination).
• Permutations come in handy when order is important. Arranging tasks in a to-do list, or scheduling meetings for different time slots, all benefit from permutation calculations.
• Combinations are important for secret codes. The order you type digits in a PIN or lock code matters (combination), unlike choosing flavors for a smoothie (permutation).
• Permutations are key in games where order decides the winner. From finishing positions in a race (permutation) to picking lottery numbers (combination), both concepts play a role.
• Both permutations and combinations are used in probability calculations. This applies to things like cybersecurity, where understanding how many key combinations exist helps assess hacking difficulty.

## FAQ’s

What is the main difference between permutation and combination?

Permutation considers order, while combination does not. Permutation results in distinct arrangements, while combination focuses on selections.

What is permutation and combination with an example?

Use permutation for ordered arrangements (e.g., seating). Use combination for selections without order preference (e.g., committees).

How do you know when to use permutation or combination?

Permutation involves ordered arrangements, yielding distinct outcomes. Combination focuses on selections, disregarding order for similar outcomes.
