-O.25 is not the probability of an event because it does not lie between the value of 0 and 1.
Step-by-step explanation:
The probability of an event is the measure of the chance that the event will occur as a result of an experiment. The probability of an event A is the number of ways event A can occur divided by the total number of possible outcomes. If P(A) > P(B) then event A is more likely to occur than event B.
The probability of an event must be a number between '0' and '1' (inclusive). In words: The probability of an impossible event is '0'. In words: The probability of an absolutely certain event is '1'
