In mathmatics, a combination is a way of selecting several things out of a larger group, where (unlike permutations) order does not matter.

All forms are read aloud "n choose r."

How many different committees of 4 students can be chosen from a group of 15?

Exmaple

Real life application

Surprisingly, it is really easy to find some real life applications of combination. Whenever we order something, we use combination. For example, 1. Selecting nominies for a council2. Selecting topping ingredients for pizza.3. Selecting student officers in a classroom.

BONUS!-What is the difference between combination and permutation?If the order doesn't matter, it is a Combination.If the order does matter it is a Permutation.

This project is the hardest project in this year. Unlike other project, we have to find information and had to learn about the concept. Since combination and permutation is almost same, I was really confused. However, with help of our friend, Google and my real friends, now I can distinguish combination and permutation. When I heard that my topic is “combination”, I couldn’t anything. I thought, ‘Combination? Combine something? WHAT?’ Nonetheless, when I just began my research, I just realized what combination is. Additionally, I realized that combination is really important in our daily life. Whenever I order something, I probably use the concept of combination although I don’t recognize it. This project helped me to understand both combination and permutation while I making this glogster poster. Additionally, I would learn other topics such as probability with my poster what my group member made. I really enjoyed this project and I was great! This project is the hardest project in this year.
