#1**+10 **

**Good question!**

Say you have 3 objects A,B, and C

All the combinations of 2 are AB,AC, and BC there are no others There are 3 combinations of 2 objects

The order that the objects are selected in is **NOT** important.

BUT

All the permutations of 2 are AB, BA, AC, CA, BC, and CB There are 6 pemutations of 2 objects

You see, **with permutations the order is important**!
