Probability is the likelihood or chance that something will occur. Probability is an indicator of their relative average frequency with which an event happens in repeated independent trials. The relative frequency is always between 0% (the event occurs) and 100 percent (the event always occurs). Probability provides us an instrument to forecast an event will occur, but doesn’t allow us to predict an event will happen. Probability may be employed to ascertain the requirements for obtaining a game’s long-term fiscal prospects or certain results; it might help determine if there is a game really worth playing with. It’s often expressed as odds, a percentage or a decimal fraction (also known as a proportion). Probability and odds are different methods of describing a player’s chances of winning a wager.

Probability, Random Events, and the Mathematics of Gambling
Probability is an indicator of the possibility of winning divided by the total number of chances out there. Probability is an ordinary fraction (e.g., 1/4) which can also be expressed as a percentage (e.g., 25%) or as a proportion between 0 and 1 (e.g., p = 0.25). Whether there are four tickets in a draw and a player owns one of these, their odds of winning is 1 in 4 or 4 1/4 or 25 percent or p = 0.25.
