What is the chance, or probability, of rolling a 2 on a single die?

Probability is the number of outcomes we want, or desired outcomes, divided by the total possible number of outcomes.

There is one way to roll a 2 with a single die and just one roll. And there are 6 ways that a single roll can land, so our probability is 1 divided by 6

If we want, we can make this into a decimal by dividing 1 by 6, or even a percent, which would be 16.6 percent
