Probability of rolling a number on a single dice
Test your understanding of probability of rolling a single die by practicing it! Work through the below exercises to use it in practice.
🎙️
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
