Lesson 5 Summary

 

The fundamental counting principle, permutations, and combinations may all be used to solve probability questions depending on the circumstances of the question. It is important to decide whether order is important or not before beginning a question, as this helps to narrow down solution possibilities.

 

When solving probability questions, you are looking for the likelihood that a particular event occurs. The answer to a probability question is always a number between 0 and 1. A probability of 0 means that the event cannot or does not occur, while a probability of 1 means that the event always occurs. Probability solutions can be written in fraction form, decimal form, or percent form.
