#### Order is Important

A *permutation *is an arrangement of objects or elements in a specific order. Sometimes it is the ordering of all the elements in a group. Often it is the order of choosing elements from a group. For example, most padlocks use three numbers between 0 and 99, but it is the order of the numbers that let’s you open the lock.

There are 3 steps to find permutations:

1. Figure out how many places there are to fill.

2. Figure out how many objects can potentially go into each place.

3. Multiply.

ExampleYou roll a 6-sided die and pull a card from a deck of 52 distinct cards. How many different pairs of outcomes are possible?

(Note: die is the singular of dice.)
