Probability

Probability is the measure of the likelihood that an event will occur, and it is expressed as a number between 0 and 1.

A probability of 0 means that the event will not occur, while a probability of 1 means that the event is certain to happen. For example, if the probability of rolling a 3 on a six-sided die is 1/6, this indicates that there is a one in six chance of that event occurring. probability scale ranges from 0 (impossible) to 1 (certain), with values in between representing varying levels of uncertainty.
