Hi Shaikshavali

I guess you have already seen these pages:

3. Permutations

4. Combinations

The main difference is that when we are considering permutations, the order is important. So we regard a,b,c,d as different to a,d,c,b.

For combinations, the order is not important. So a,b,c,d is considered the same as a,d,c,b.
