Permutations with Repetitions

When we have repetitions in a permutations question, it means there are fewer variations in the final result. This is part of the Prelim Maths Extension 1 Syllabus from the topic Combinatorics: Working with Combinatorics. In this post, we will explore Permutations and combinations permutations with repeats.

Here we will learn to solve problems involving permutations and restrictions with or without repeated objects.
