## How many different combinations can you get with 2 dice?

Note that there are **36** possibilities for (a,b). This total number of possibilities can be obtained from the multiplication principle: there are 6 possibilities for a, and for each outcome for a, there are 6 possibilities for b.

## How do you calculate the number of possible combinations?

The **formula** for **combinations** is generally n! / (r! (n — r)!), where n is the total number of **possibilities** to start and r is the number of selections made. In our example, we have 52 cards; therefore, n = 52. We want to select 13 cards, so r = 13.

## What are the outcomes of rolling two dice?
