Permutation problems are for lists where order matters where as combinations are for groups where order does not matter
Step-by-step explanation:
See permutation as the number of arrangements or orderings that can be identified from a fixed group.Here every detail about the group is important.
For example you have five teachers and you want to determine how many ways they can sit in five chairs. You notice that the number in this group is fixed, 5, and you want to know the number of ways you can arrange the teachers in five chairs.
Combination will come in when you want to determine the number of groups you can form from a given large number of individuals.
For example, there are seven pilots who are trying out to be part of a three-person in space flight team.How many different flight teams can be formed?..Here the word choose has been used to mean selecting from a group.The order of picking the three pilots from the 7 pilots does not matter. You have certain number of persons and you want to know how many arrangements are present for all of them.
