at eunjung part I'm pretty sure to listening hyomin's voice 😂❤

Combinations and permutations What's the difference? In English we use the word "combination" loosely, without thinking if the order of things is important. "My fruits are a combination of apples, grapes and bananas." We don't care about what order the fruits are in. They could also be "bananas, grapes and apples" or "grapes, apples and bananas". It's the same fruit salad. "The combination to the safe is 472". Now we do care about the order. "724" won't work, nor will "247". It has to be exactly 4-7-2. So, in mathematics we use more precise language. When the order doesn't matter, it is a combination. When the order does matter it is a permutation. We should really call this a "permutation lock"! A permutation is just an ordered combination.
