It all began in the 1650's in the city of France where gambling became popular, and it became the thing to do. As games became more complicated and the stakes became higher it was time to find a way of computing chances. (Polansky) This was when someone needed to step in. A gambler than consulted a man by the name of Blaise Pascal, he questioned him about the games of chance. And so between Pascal and his friend Pierre Fermat, they came up with the origin of the mathematical study of probability. This method that they used was called the classical approach. This method stated that suppose a game has n equally likely outcomes, of which m outcomes correspond to winning, then the probability of winning was m/n. For years people edited, disagreed and changed their belief and ideology of chance. But this, this is where probability began.
             Probability is the proportion or percentage of the time that specified things happen. The term probability is also used in reference to the art and science of determining the proportion or percentage of the time that specified things happen. (Spiegel) In mathematics according to the encyclopedia is the assignment of a number as a measure of the "chance" that a given event will occur. In all experiments there are certain possible outcomes; the set of all possible outcomes is called the sample space of the experiment. The probability of something happening is greater than zero but less than one.
             There are all kinds of ways to use probability. You can use it inference to observing evidence in court, gambling, acceptances to anything in society, and to anything that has a chance or opportunity of something else.
             In order to understand probability we must understand certain terms used in probability, these terms consisting of events, outcome and sample space. An event is defined as a single occurring or trial of the experiment, where as an outcome is the result of an event. For example, if ...
