Alright, parents and JC2 students! Feeling the pressure of H2 Math, especially when permutations and combinations come up? Don't worry, lah! This is one topic that, once you understand the fundamentals, can actually be quite fun. Let's dive into permutations, where order is super important. Think of it like arranging your favorite figurines – the order you put them in makes a big difference, right?
Permutations deal with arrangements where the sequence matters. If you're picking a team captain, vice-captain, and treasurer from a group, that's a permutation because the order determines the role each person gets. Swapping the captain and vice-captain creates a different arrangement.
Fun Fact: Did you know that the concept of permutations has been around for centuries? Mathematicians in ancient India and Greece were already exploring these ideas!
The number of permutations of 'n' distinct objects taken 'r' at a time is given by:
nPr = n! / (n-r)!
Where:
Let's say you have 5 books (n=5) and want to arrange 3 of them on a shelf (r=3). The number of different arrangements is:
5P3 = 5! / (5-3)! = 5! / 2! = (5 x 4 x 3 x 2 x 1) / (2 x 1) = 60
So, there are 60 different ways to arrange those 3 books!
Things get a little more interesting when we add constraints. What if two specific books *must* be next to each other?
Example: Arrange 5 books where book A and book B must be together.
What happens when some of the objects are identical? For example, arranging the letters in the word "APPLE". The two "P"s are identical, so swapping them doesn't create a new arrangement.
The formula for permutations with non-distinct objects is:
n! / (n1! * n2! * ... * nk!)
Where:
Example: How many ways can you arrange the letters in the word "BANANA"?
Arrangements = 6! / (3! * 2! * 1!) = 720 / (6 * 2 * 1) = 60 ways.
Interesting Fact: Permutations are used in cryptography (the science of secret codes) to generate different key arrangements!
