Understanding the Concepts of Probability

Probability is the possibility that an event will occur. A probability is a number that represents the chance or likelihood that a specific event will take place.

A probability of 0 implies that an event has no possibility of occurring, whereas a probability of 1 suggests that an event is almost certain to occur.
