Probability of rolling a single die

Teaching Transcript

🎙️

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

This math skill teaches how to calculate the probability of rolling a specific number on a die. It explains that the probability is determined by dividing the number of favorable outcomes (rolling the desired number) by the total number of possible outcomes when rolling the die once.
