A gambler's dispute in 1654 led to the creation of a mathematical theory of probability by two famous French mathematicians, Blaise Pascal and Pierre de Fermat. The probability of an event A, symbolized by P(A), is a number between 0 and 1, inclusive, that measures the likelihood of an event in the following way: If P(A) > P(B) then event A is more likely to occur than event B. It is quantified as a number between 0 and 1, with 1 signifying certainty, and 0 signifying that the event cannot occur. To recall, the likelihood of an event happening is called probability.
