**What is the counting rule?**

Fundamental Counting Principle Definition. The Fundamental Counting Principle (also called the counting rule) is a way to figure out the number of outcomes in a probability problem. Basically, you multiply the events together to get the total number of outcomes.

### How do you do permutations?

**What’s the difference between permutations and combinations?**

What do you mean by permutations and combinations? A permutation is an act of arranging the objects or numbers in order. Combinations are the way of selecting the objects or numbers from a group of objects or collection, in such a way that the order of the objects does not matter.
