Probability concerns events and numerical descriptions of how likely they are to occur. The probability of an event is a number between 0 and 1; the larger the probability, the more likely an event is to occur. [note 1][1][2] This number is often expressed as a percentage (%), ranging from 0% to 100%.
The probability of an event can only be between 0 and 1 and can also be written as a percentage. The probability of event A is often written as P (A) . If P (A)> P (B) , then event A has a higher chance of occurring than event B . If P (A) = P (B) , then events A and B are equally likely to occur.
