Probability As A Fraction, Decimal Or Percentage
Overview
Probability measures how likely something is, on a scale from impossible to certain. The same likelihood can be written as a fraction, a decimal or a percentage, and being able to move between them is the first skill of the topic.
In this lesson you will calculate the probability of a single event as a fraction, decimal or percentage, understand the 0 to 1 scale, and use the fact that the probabilities of all outcomes add up to 1.
Objectives
- Express the probability of an event as a fraction, decimal or percentage, and interpret the significance of its value.
