Updated: 4/28/2022

An event which has a probablility of 1 is one that will definitely happen. Probabilities range between 0 and 1 (0% and 100%) with a probability of zero meaning it is impossible and a probability of one meaning that it is definite. i.e. winning the lottery if you never play has a probability of zero and winning the lottery if you know the correct numbers in advance has a probability of one.
