What is Probability?

Probability is a measure of the likelihood that an event will occur. It is expressed as a number between 0 and 1, where 0 indicates impossibility and 1 indicates certainty. Probability can also be expressed as a percentage (0% to 100%).

Frequently Asked Questions

How do you calculate probability?
Probability is calculated by dividing the number of favorable outcomes by the total number of possible outcomes: P(event) = favorable outcomes / total outcomes.
