Detailed Important Topics of RS Aggarwal Class 11 solutions Chapter 9
In Chapter 9 of the RS Aggarwal Book for Class 11, you will learn about things like what a combination is, how it differs from a permutation, how to solve problems using the combinations property, how to solve problems using the combinations formula, and how to solve problems using both permutations and combinations.
Combination is a way to figure out the total results of an event when it doesn’t matter what order the results come in at the end. Using the formula, you can easily find the sum of the results:
nCr = n! / r! * (n – r)!
Here, “n” stands for the total number of items, and “r” stands for the number of items you can choose at once.
How a permutation is different from a combination
The main difference between permutations and combinations is how they are put together. In permutations, the order of the elements matters, but in combinations, it doesn’t.
Most of the time, you can say “arrangements” for “permutations” and “selections” for “combinations.”
